T41 200

American-inspired locomotive

In 1953, Nohab began manufacturing diesel locomotives under licence from the American General Motors (GM), initially for the Danish state railways. Two of the most famous models were the TMX and TMY. A few years later, in 1955, SJ also ordered five locomotives of the same type. The design followed the American model with two three-axle bogies and a GM engine.

Adapted for Swedish railways

An important feature of these locomotives was the low axle load of only 14 tonnes, which meant that they could run on tracks that were a little thinner. Unlike the Danish locomotives, the Swedish ones were built as single-cab locomotives, which means that they had one driver's cab instead of two. The cab was positioned so that the locomotive had one longer and one shorter hood, giving them a distinctive look.

Brown design and new names

The Swedish locomotives were painted in a stylish brown colour with white stripes. They were originally called T4, but in 1961 they were renamed T41. Their numbers were also changed - at the time of delivery they had numbers in the 100 series, but this was adjusted a few years later.

These locomotives became an important part of SJ's fleet and are still of interest to railway enthusiasts and the technologically curious alike!
