The Swedish steam locomotive type E10 was a locomotive for freight traffic . They were mainly used in the domestic railway sector.

history

Nydqvist och Holm in Trollhättan received the construction contract from Statens Järnvägar for the E10 series . The locomotives were given the road numbers E10 1739–1748 . The locomotive has three steam cylinders and is equipped with large smoke deflectors named after Richard Paul Wagner .

The locomotives delivered in 1947 have four driving axles and a two-axle running bogie at the front. They were with a triaxial Wannentender equipped type G5.

When delivered, the E10 1739–1743 were coal-fired and the E10 1744–1748 were oil- fired . Over time, the locomotives have been converted several times for oil or coal firing, depending on the fuel prices.

The series got the designation E10 after the G12 42-47 locomotives taken over from Halmstad – Nässjö Järnväg (HNJ) in 1945 had received the series designation E9 after the nationalization of the private railway . The people in charge at SJ were impressed by the characteristics of these locomotives, such as the low axle load, high tractive power and good track guidance. This is why the E9 formed the technical basis for the E10 locomotives. The E10 differed from the E9 in terms of roller bearings, closed cabs and the type G5 tender .

commitment

After delivery, the E10 series was used on the Östersund - Mora , Storuman - Vilhelmina , Hoting - Storuman and Dorotea - Storuman sections of the Inlandsbahn and on the Orsa - Bollnäs railway line . The oil firing caused locomotive shed fires , including 1958 in Östersund, where E10 1745 and E10 1748 were badly damaged.

In the 1960s, a few copies became emergency locomotives ( Swedish "Beredskapslok" ) and remained in working order. The remaining machines were shut down around 1973 and then scrapped.

Museum locomotives

E10 1744 in Grängesberg. The locomotive, which was parked in poor condition in 2004, was part of the Beredskapsreserve

After the war readiness reserve was dissolved in 1991, the locomotives that had been in existence until then were largely preserved as museum locomotives.

The following museums are in possession of E10 locomotives:
