Tinnsjø railway ferry was a Norwegian railway ferry service on the lake Tinnsjø that connected the railways of Rjukanbanen and Tinnosbanen. The 30 km long ferry trip made it possible for Norsk Hydro to transport its fertilizer from the plant at Rjukan to the port in Skien. The ferry services operated were operated by Norsk Hydro from 1909 to 1991, when the plant closed. One of the ferries was in 1944 the target of the Norwegian heavy water sabotage when it was sunk to 430 meters depth to prevent Nazi Germany from developing nuclear weapons.[1]

The transport chain from Rjukan to Skien consisted of four sections:

  • Rjukanbanen, railway line from Rjukan to Rollag (Mæl), 16 km
  • Tinnsjø railway ferry from Rollag to Tinnoset, 30 km
  • Tinnosbanen from Tinnoset to Notodden, 34 km
  • Telemark canal from Notodden to Skien, 54 km with barge
  • In 1919 the canal was replaced with the railway Bratsbergbanen from Notodden to Skien.[2]

[edit] History

Norsk Hydro was founded in 1905 by Sam Eyde as a Norwegian fertilizer manufacturer, and the first factory was opened in Notodden. Fertilizer factories need a lot of energy, and then it was necessary to locate the plants near hydroelectric power plants, and at Rjukan there was a large waterfall. In 1911 Rjukan Salpeterfabrikk was opened.[3]

The Tinnsjø railway ferry service was opened in 1909 along with Tinnosbanen and Rjukanbanen. The two lines were the second railway line in Norway, after Thamshavnbanen, to be electrified in 1911. The railway service utilised Telemark Canal until 1919 when Bratsbergbanen opened from Notodden to Skien. The railway was used both to transport raw materials to the factory and to transport the finished fertilizer to the harbour at Skien. There was also passenger trains that ran.

In 1929 Norsk Hydro also establish itself at Herøya in Porsgrunn, and in 1991 the factory in Rjukan, and therefore also the railway line, was closed. The passenger trains, operated by Norges Statsbaner, had been discontinued already in 1970. In 1997 the ownership of the track was transferred to Stiftelsen Rjukanbanen, a foundation that started heritage operation of the line in 1999.

The railway ferry service was provided by four different ships, D/F Rjukanfoss, D/F Hydro, D/F Ammonia and M/F Storegut. The three first were steam ships, and the latter two are still docked at Mæl. The service was the only ever railway ferry service on a lake in Norway, and D/F Ammonia is the only remaining railway ferry steam ship in the world.[4]

[edit] D/F Rjukanfoss

D/F Rjukanfoss, built in 1909, was the first railway ferry on Tinnsjø. The steam ship was 42.2 m (138.3 ft) long and 9.8 m (32.3 ft) wide and 338 gross tonnes. It operated up to two daily departures each way, with a capacity of 120 passengers. The ship was rebuilt in 1946 to 648 gross tonnes but taken out of services and destroyed in 1969.[5]

[edit] D/F Hydro

D/F Hydro was the next ship to operate as railway ferry, entering service in 1914. It was slightly larger than Rjukanfoss, with 439 gross tonnes, 53 m (174 ft) long and with two 186 kW (250 hp) engines. On February 20, 1944 the ship was blown up by the Norwegian resistance movement at Tinnsjø's deepest point, 430 meters with a load of heavy water onboard heading for Germany.[6] It is believed that 18 people were killed while 29 survived the sabotage.[7]

[edit] D/F Ammonia

In 1929 Norsk Hydro expanded their plant, and there was need for a third ferry. D/F Ammonia was built the same year and was the largest of the three steam ships with 929 gross tonnes, two 336 kW (450 hp) engines and a length of 70.4 m (230.6 ft). It had a capacity of 250 passengers. From 1957 it was made a reserve ferry when Storegut was for service. It was taken out of service in 1991 when the railway closed, but can still be seen docked at Mæl.[8] It is the only remaining steam powered railway ferry in the world.

[edit] M/F Storegut

M/F Storegut is the last ferry and the only motor ship to operate on the lake. Built in 1956, it weighs 1119 gross tonnes, is 82.7 m (271.4 ft) long with three 1678 kW (2250 hp) diesel engines. The passenger traffic with the ship terminated in 1985, and it was taken out of service in 1991 and is docked at Mæl.[9]
