Finland’s Magnetic Island: Jussarö, A Danger to Shipping

Coastal geology & environment, Regional History, Travel

Its been called a ghost town but the island’s massive concentration of iron ore under the sea⧆ exerts a powerful magnetic pull on passing ships and boats. The island of Jussarö is one of some 40,000 (and counting) islands off the coast that form Finland’s vast archipelago⌖.

The “ghost town” tag comes from the closure of the island’s iron ore mining works in 1967☯ due to a decline in the world price for the mineral (‘Jussarö’, www.en.jussaro.net) …leaving the landscape scattered with the remnants of old industrial buildings abandoned to nature.

Compass interference, a danger to shipping
The dense concentration of iron ore deposits within the island has been known to make the navigation equipment of passing vessels in the Gulf of Finland go haywire. The magnetic force emitted by the island tends to make ships malfunction and their compasses point in the wrong direction. Historically, a consequence of this has been a large incidence of marine accidents and shipwrecks in the vicinity. In 1468 the Hanseatic League cargo ship ‘Hanneke Wrome’ (or ‘Vrome’) was caught in a storm and wrecked near Jussarö island with the loss of over 200 lives and a vast quantity of expensive fabric, barrels of honey, gold coins and jewellery (‘Finland’s abandoned iron ore mine’, Abandoned Spaces, Bojan Ivanov, www.abandonedspaces.com). Perhaps the most famous shipwreck, known as “Jussarö I”, is a early 16th century ship belonging to the fleet of Swedish king, Gustav I Vasa (‘Jussarö Island’, www.visitraseborg.com). Given this hazard, Jussarö has been a haven for pilot stations and lighthouses (the island’s earliest pilot station dated from early 19th century).

Raseborg’s teeth “ship trap”
Several smaller islands and islets south of Jussarö collectively known as Raseborgs gaddama (Raseborg”s Teeth”) are particularly prone to shipwrecks. This area is known to have caused disturbances in navigation as early as the 17th century. In 1751 Swedish naval cartographer “Jonas Hahn was able to explain the phenomenon by the high iron content in the underwater rock formation in the area”. The Sundharu lighthouse was stationed on one of the skerries here to try to counter the danger (‘Finnish cases: Four case study areas. Case 1 – Jussarö ship trap’, www submariner-net.eu).

When the mining activity ended, Jussarö was taken over by the Finnish Defence Forces and used for military training and urban war simulation. After the army left in 2005 the island came under the administration of Metsähallitus, a state-owned authority in charge of national parks, wildlife and forestry. The main activity today is tourism with day-trippers regularly commuting from the mainland.

Postscript: The island’s 13th century footnote in history
Jussarö first gets a mention in medieval Danish documents, appearing in King Valdemar II’s Survey (or “Court Rolls”), a document compared to William the Conqueror’s Doomsday Book record. The ‘Survey’ of Valdemar II of Denmark (reigned 1202–1241) was a land register of Danish settlements and their populations, c. 1231 (Nils Hybel, The Nature of Kingship c.800–c.1300: The Danish Incident , (2017)). Jussarö is included in the royal survey apparently because it was on the Danish route map (www.en.jussaro.net).

A Place to Sell Fish in Sydney in Very Large Quantities: From Woolloomooloo to Blackwattle Bay

Commerce & Business, Local history, Old technology

Pyrmont on the edge of Sydney’s CBD is one of those inner-city suburbs which has undergone the dramatic effects of intensive urban renewal since the turn of this century – the traditional industries such as sugar refining, brewing, ship and boat-building, the old working class pubs, the modest workers” cottages have all given way to media and IT firms and high-rise apartments. One of the relatively few industry survivors in Pyrmont is the Sydney Fish Market on Blackwattle Bay.

Fish Market, Woolloomooloo (Photo: State Lib of NSW)

Rudimentary beginnings at Woolloomooloo
The city’s fish market has been a local Pyrmont landmark, a continuing presence since 1966, but the city fish market’s history extends back much further than that. It was originally located on the corner of Bourke and Plunkett Streets, Woolloomooloo, on the eastern fringe of the CBD…the selling of fish here in a methodical fashion of sorts commenced in 1871 (some references give the year as 1872).

Eastern Markets, Wolloomooloo: an absence of tables (Photo: SFM)

These Woolloomooloo “Eastern Markets”, according to newspaper reports of the time, show that it was much maligned for its deficiencies. The litany of complaints included its position, deemed far from central; the “barbarous nature of internal arrangements”, ie, the unsanitary practice of laying fish for sale on the uncovered market floor; logistics and transportation shortcomings, ‘transhipment’ was inordinately lengthy: hauls were transferred from catcher to small steamer to large steamer, dumped on the wharf at Botany port until carted to the market by wagon❈ and subjected to pilfering and deterioration on route; the whole process necessitating “maximum amount of handling (of) a peculiarly delicate commodity which suffered from unnecessary pulling and hauling” [‘City of Sydney Improvements’, Evening News (Sydney), 21-Nov-1891].

A developing fish market rivalry
With dissatisfaction with the Woolloomooloo markets palpable, a second fish market was established at Redfern in 1891 which came to be known as the “Southern Fish Markets”. The Redfern enterprise was a clear improvement on Woolloomooloo which had come came under the control of the City of Sydney Council circa 1907-1908. Redfern was conveniently situated adjacent to the railway station. Rail-transporting the fish eliminated the need to load and reload the goods several times, the process was more timely so the fish arrived fresher and in “marketable condition” (plus it meant lower freight charges by rail). Other advantages were new features like cool storage chambers and dedicated rooms for  “smoke curing”. Redfern also had the bonus of being elevated, necessary to facilitate the draining of the seafood. Most crucially Redfern was a step up on hygienic fish presentation, placing them not on the floor but in specially constructed tables (around this time Darling Harbour was also mooted as a alternate venue for the fish markets but was considered not as good a site as Redfern)(‘Evening News’).

Redfern residents however were not enamoured of the fish market in their suburb, as a result of the uninvited 4am “wake-up calls” each morning: the approaching “rumble of fish carts and the vulgar ejaculations and rude raillery of the hawkers” [‘1872 First Sydney Fish Market’,
Australian Food Timeline, www.australianfoodtimeline.com.au].

Fish market built in Haymarket, 1910 (Source: City of Sydney Archives)

Council market v private market
Sydney Lord Mayor, Alderman Taylor, in 1909 advocated relocation from Woolloomooloo to the Belmore Fruit and Vegetable Markets (where Capitol Theatre is situated today) [‘Sydney Fish Market. its Early History’, by Mary Salmon, Evening News, 02-Jul-1909]. This subsequently came to nought, instead in 1910 a new fish market was built a short distance from there at Quay Street, Thomas Street and Thomas Lane, Haymarket (today housing the Prince Centre), and run by the City Council Fish Market in direct competition with the privately-run Redfern operation.

Woolloomooloo continued for a time after Haymarket got going but in a much reduced form with some confusion about its status, as a contemporary article in the Sydney Sun pointed out, the Woolloomooloo manager in 1915, rejecting its description as a fish market, in a piece of double-speak referred to it as a “distribution centre”, adding that it was “merely a market incidentally. If there is any surplus of fish for sale it will be sold” [‘Not a Fish Market: Woolloomooloo Depot”, The Sun, 28-May-1922. In 1926 high profile businessman John Wren purchased the “old Fish Markets” premises at Woolloomooloo (Daily Telegraph, 04-Dec-1926) which was demolished in the 1960s, making way for the Astor Apartments.

Squeezing out the private market
The Council was determined to end the fish market rivalry with Redfern. The state government did its part to assist by refusing to renew the licenses of fish agents at the Southern Markets. Despite a view that the Quay Street fish market was not a paying concern (it was claimed that it handled only 20% of the consigned fish coming to Sydney), a bill was passed in state parliament in 1922 which allowed the City Council Market to acquire the assets of the Redfern fish exchange, which forced its closure the following year [‘Fish Fight: Council v. Redfern Markets’, The Sun, 03-May-1922. Woolloomooloo continued for a time but in a much reduced form with some confusion about its status, as a contemporary article in the Sydney Sun pointed out, the Woolloomooloo manager in 1915, rejecting its description as a fish market, in a piece of double-speak referred to it as a “distribution centre”, adding that it was “merely a market incidentally. If there is any surplus of fish for sale it will be sold” [‘Not a Fish Market: Woolloomooloo Depot”, The Sun, 28-May-1922].

FMA fish monopoly
The Haymarket fish market continued as the sole conduit for fish trading in Sydney until 1945 when their monopoly was expanded…the government transfered the marketing and selling of fish to the NSW Chief Secretary’s Department (hitherto unlicensed operators could sell fish outside of Sydney) which established a regulated and centralised market for the entire state. The central fish market’s control was consolidated in 1964 with the creation of the Fish Marketing Authority, a NSW statutory authority under the jurisdiction of the Department of Agriculture¶ (‘Market History’, Sydney Fish Market,  www.sydneyfishmarket.com.au]. The FMA’s role was to bring the seller’s fish and the buyer together, charging a percentage fee for this service.

“Next up, same boat mullet!”
Relocated to Pyrmont in 1966, the fish market management employed a ‘voice’ auction system, buyers would position themselves around the selling bay and as the auctioneer’s called each lot’s sale, they would verbally bid. Disputes among buyers were not uncommon given the din of noise present and with such a capricious arrangement.

Dutch flower market auction
In 1989 the FMA introduced a computerised Dutch auction system used in Amsterdam to sell tulips, replacing the old manual system. It works by setting the start price approximately $3 higher than the anticipated selling price and then lowering it until a registered bidder electronically lodges a bid [‘Sydney Fish Market’, www.pyrmonthistorygroup.net.au]. This innovation has made the auction process more efficient and quicker.

Privatisation and de-regulation 
The  state-run markets were privatised in 1994 and renamed Sydney Fish Market P/L. In 1999 full de-regulation meant catchers in NSW could now sell directly to any buyer with a Fish Receiver’s Permit, bringing to an end the Pyrmont market’s long monopoly over the sale of seafood in Sydney (private ownership of the market made the continuation of monopoly untenable) (‘SFM’).

The SFM at Pyrmont in 2021 is the largest seafood market in the Southern Hemisphere and one of the biggest in the world. Every hour of it’s commercial operation about 1,000 crates or 20,000 km of seafood gets sold (‘SFM’).

End-note: An intriguing sidelight to the operation of the fish market at Pyrmont during the 1980s (and I suspect before then as well) was the existence of a black market. As well as bona fide fish buyers, other individuals would frequent the daily markets with a view to unloading ‘hot’ merchandise or goods of a distinctly un-piscine nature for a ‘special’ price. Such shady transactions would often occur concurrently and even alongside the auction bay itself. It was that sort of place which drew all sorts of dodgy characters looking to make a quick buck, no questions asked.

The fish markets are moving again but this time staying on Blackwattle Bay, the new site will be 15,500 sq m in size, more than two-and-half times the present market, with a scheduled finish date of 2024. The new SFM promises to make the auction area more visible and accessible (off-limits to the public since the change to the computerised system).

Shinkansen, Japan’s Pioneering VFT and National Icon

New Technology,, Regional History, Sports history
Tokyo ‘64 (Source: glacerie123.com)

A symbol of modernisation
1964 was a bumper year for the Japanese. In October of that year two events helped the country finally break free of the persisting shadow of an an ultimately inglorious and painful World War II experience. Japan’s capital Tokyo staged the XVIII Summer Olympic Games and Japan launched its iconic high-speed train service, the Shinkansen (meaning literally “new trunk line” or “new main line”), popularly called the “Bullet Train” (弾丸列車 dangan ressha) because of the similarity of the initial (0 series) design of the nose✲. Together, the Olympics and the Shinkansen’s arrival symbolised the fulfilment of “Japan’s recovery from the devastation of war and the beginnings of Japan’s stratospheric rise as an economic superpower” (Braser & Tsubuku)⌧.

Planning for the Shinkansen started in the 1950s and had its origins in the realisation that Japan’s conventional rail network was reaching capacity and not up to the demands of modernisation. The country’s geography, climate and population needed a faster, modern network. A VFT was identified as imperative for a land mass that stretched over several islands north to south for thousands of kilometres. Construction (and operational) challenges were manifold and extremely formidable – a mountainous country subject to earthquakes, typhoons, heavy rain and snow and flooding (Hood).

The original rail service, the Tōhoku Shinkansen connected the three principal cities on Honshu island, Tokyo, Nagoya and Osaka. The impact on intra-Japan rail travel was immediate and dramatic. With the sleek “whiz-bang” new train reaching speeds of up to 210 km/h⍟, the journey between Tokyo and Shin-Osaka was cut from 6 hrs & 30 mins in an conventional train to around 4 hrs & 10 minutes in the Bullet Train! (in 1965 it was reduced again by a further hour)✪.

An accident-free record
As impressive as it is, the Shinkansen’s most impressive attribute is not its rapid speed, but its peerless safety history over a period of 57 years. The Shinkansen service has not suffered a single casualty or even one injury in the totality of its trips. The only blots on the perfect record in this time have been two derailments (one in an earthquake and one in a blizzard) (Glancey).

Rail privatisation
Originally the Shinkansen train network was built and operated by the Japanese government (Japanese National Railways), but in 1987 it was privatised, coming under the ownership of six Japanese Railways Group (JRG) companies. Today they runs nine separate lines, smoothly criss-crossing the densely-populated Honshu and Kyushu islands and extending to the northern island of Hokkaido, it’s spotlessly clean carriages carrying an average of around 150 million passengers a year (JapanRail Pass). The network has two types of Shinkansen trains – Kodama Express and the limited stop Hikari Super Express train.

Personifying Nihongo efficiency
The latest iteration of the Shinkansen, the N700 train with its aerodynamic duckbill-nose completes the Tokyo–Osaka journey in 2 hrs & 25 mins⌽. The N700S (Supreme) has the advanced capacity to continue operating during earthquakes. Punctuality is also the Shinkansen’s strong suit – the average delay for the railway’s fleet of trains is less than 60 seconds (Dow). The Shinkansen’s efficiency represents “an elegant solution for shuttling workers from one dense city to another” and doing it rapidly, workers living “in distant, relatively undeveloped areas can commute to Tokyo (for instance) in two hours” (Pinsker).

Local dissenters to the “love affair” with the Shinkansen
The Shinkansen has been a change agent for Japanese economy and society, a potent symbol of the nation’s development. Research indicates that those urban hubs with a Shinkansen station experience higher population and higher employment growth rates (Sands). Not everyone in Japan however is 100% behind the Bullet Train companies’ unbending “full-steam ahead” approach. There have been pockets of local rural opposition pushing back against JRG’s relentless land acquisition process. Residents along the routes whose quality of life has been adversely affected by Shinkansen’s noise and vibration have also been vocal in their complaints (Hood).

Japan’s Maglev prototype (Source: ft.com)

Eye on the future
Not resting on the laurels of the Shinkansen series’ cutting-edge technology, research has been happening since 1962 on a linear motor railway system. In the 2000s JR Central commenced testing a Maglev train prototype, the Linear Chūō Shinkansen, which can reach a speed in excess of 500 km/h – this service is slated for introduction in 2027 (Nippon.com).

Postscript: To transfer technology or not to transfer technology?
Japan’s success with the Shinkansen has spawned imitators. China’s vaulting high-speed train ambitions—while denying charges of intellectual piracy by copying the Shinkansen—has seen it have to resort to reliance on German and French as well as Japanese VFT technology for its own high-speed train. Consequently some Japanese railway insiders have criticised the technology leak to China, lamenting that when you put high technical ability on display (as Japan has with its crown jewel train), it gets copied. However there’s no consensus on this point within Japanese government and business. Central Japan Railway Co (owner of Shinkansen and Linear Train Technology) have actively participated in the development of US high-speed trains on an ongoing basis, proponents of this approach argue that by not exporting the Bullet Train technology to countries with large markets, Japan risks losing out to competitors who’ll get in first…the Overseas Rapid Railway Project’s Katsunori Ochiai summed up the gains from exporting: “If the new Japanese model Shinkansen and linear trains are adopted in America, the market for manufacturers of the carriages and signal systems would be greatly expanded.” (Shimbun).

Shinkansen technology transfer’ first export overseas was to Taiwan, successfully helping to develop the Taiwanese High-Speed Rail system.

L’Aérotrain Experiment: The Rise and Fall of a French Hovertrain

New Technology,, Regional History, Science and society

Before the Maglev (magnetic levitation) very fast train (VFT) system was developed—which we can observe today in commercial operation in Japan, China and South Korea—there was the Aérotrain prototype in France✳. Its story starts in the early 1960s when France was faced with a need to revitalise its declining railway sector. In 1963 aviation engineer Jean Bertin pitched his Aérotrain concept for a VFT mass transit system to France’s public transport czars. Over the next two years the government created a state company to study the Aérotrain while Bertin developed his 1:20 scale model train into the full-scale prototype.

Bertin’s invention was a Tracked Air Cushion Vehicle (TACV), a hovertrain riding on a cushion of air atop “a simple reinforced concrete track or guideway”∆. The Aérotrain design borrowed from the lifting technology of hovercraft vessels and from the arliner’s turbo fan. Both the ‘wheelless’ vehicle and the T-shaped track were radical designs at the time. Bertin’s intention was to come up with a simpler and cheaper alternative to the Maglev trains then in experimentation (‘France’s Aérotrain’, Ian Brown, Google Sighting, 10-Oct-2013, www.googlesighting.com).

Exporting the hovertrain
By 1966 Bertin & Cie had built its first Aérotrain test track (6.7km-long) at Essonne, south of Paris. Interest in Bertin’s hovertrain concept was international, Britain designed its own version, the RTV-31 Tracked Hovercraft, and constructed a test track in 1970, in the US, Rohr Industries contracted with Bertin’s company to do the same. Bertin developed several prototypes, the ultimate bring the Aérotrain 180 HV, a 25.6m-long hovertrain seating 80 passengers and attaining a world record speed for overland cushion vehicles (430.3 km per hour).

Technical issues
L’Aérotrain prototype presented Bertin with a series of design challenges — the system would require new elevated guideways for every implementation; the craft when passing other trains or entering tunnels experienced sudden changes in air pressure; the Aérotrain’s gas turbines operated with giant propellers which generated tremendous noise, necessitating a reduction in speed in urban areas (making it unattractive to some interested authorities) (‘Aerotrain’, Wikipedia, http://en.m.wikipedia.org).

Aérotrain, not the people’s train?
Although the technocrats in the state apparatus were favourably disposed to Bertin’s Aérotrain—especially DATAR (Delegation for Territory Planning and Regional Action)—its acceptance was not universal within France. Technical difficulties like the noise levels turned . many Parisians away from the vehicle. With such a “cutting-edge” special project, a perception grew that Aérotrain travel was for the elite commuter, not the average French worker, “(serving) only a rarefied strata of society” (Guigueno, Vincent. “Building a High-Speed Society: France and the Aérotrain, 1962-1974.” Technology and Culture, vol. 49, no. 1, 2008, pp. 21–40. JSTOR, www.jstor.org/stable/40061376. Accessed 20 June 2021).

180 HV Aérotrain Expérimental

Cost was increasingly a factor working against the Aérotrain, the system, requiring a dedicated track would be costly to implement. The 1973 oil crisis (also see End-note) and the imposition of new strictures on state spending didn’t help, leaving the Aérotrain Company in financial difficulties (Guigueno). Public authorities were increasingly reluctant to fund the Aérotrain project.

SNCF (Photo:www.france24.com)

The modern versus the traditional
The bureaucracy and SNCF (French National Railway Company) had its own agenda, which deviated from the objectives of Aérotrain. Transport planning in France was committed to a policy of maintaining the efficacy of “traditional modes of urban transport”, heavily investing in Aérotrain ran counter to that. The influential SNCF saw it as a “competitive threat to the traditional railway” (Guigueno).

Pres. Giscard d’Estaing (Photo: Multimedia Centre)

The lethal blow came in 1974. French president, Georges Pompidou, who had been a moderniser, died. His more conservative replacement, Valéry Giscard d’Estaing, coming down on the side of traditional technologies terminated the Aérotrain project just two months into office. The reasons for Giscard’s opposition to the project are not certain, Guigueno speculates that perhaps the president was reacting to Aérotrain’s unpopularity with the Paris suburbs and their representatives. The recently-approved Cergy—La Défense link for Aérotrain engendered scepticism from locals due to delays and cost overruns and was also canned by Giscard. Giscard whose previous ministerial job was controlling the nation’s pursestrings probably thought Aérotrain was too much of a financial risk at the time (‘Transport That Never Was Part 1: Aérotrain, a hovertrain in Paris’s western suburbs’, Fabric of France, 18-Feb-2020, www.fabricoffrance.com).

TGV Hi-Speed Train (Photo: EURail Pass)

Replacing a revolutionary VFT with a conventional VFT
Aérotrain’s misfortune was TGV’s good fortune. The Giscard government switched from Aérotrain to TGV¶, a rival turbo train design inspired by Japan’s Shinkansen, as the preferred provider for France’s inter-city high-speed rail service. In 1981 TGV became the VFT carrier for the new Paris to Lyon link. Essential to TGV’s triumph over Aérotrain was SNCF’s strategy of “develop(ing) TGV as a supplement to, rather than a replacement for the traditional rail service” (Guigueno)❂. On the matter of infrastructure TGV was a full circuit in front of Aérotrain. The TGV was a better fit with its huge advantage over Aérotrain in compatibility with existing railways in France, and it could extend, beyond the high-speed network, over much greater distances (‘Transport That Never Was’).

Abandoned Aérotrain test track near Orléans: section of Saran—Ruan monorail still in existence

Aérotrain’s eclipse was devastating for its inventor … Bertin, already stricken with cancer, died several months later, aged just 58. In 1977 the Aérotrain project was abandoned, bringing an end to the Gallic hovertrain dream.

End-note: The hike in the world oil price after 1973 posed an acute problem for the TGV prototype, being as it was powered by gas turbines. Sagely, the company switched its prototype to all-electric trains to overcome this, and stay cost-competitive with Aérotrain (‘Transport That Never Was’).
