The Swedish Transport Administration’s new wagon takes shape

The development phase of the design of a new apparatus wagon for the Swedish Transport Administration is completed and the project is now entering production preparations.

The apparatus wagon will have walls made of self-supporting sandwich elements that are fixed between the frame and the roof. Among the advantages of using self-supporting elements is that no welding is required and that pre-painted parts can be used. The new apparatus wagon will have standard draw and buffing gear at both ends, unlike the original wagon, Q49, which only had these functions at one end.

What makes this wagon stand out, however, are the wheelsets and the suspension; the dimensions of the axle and wheel diameter are non-standard and Kiruna Wagon has tackled this by using standard parts and an adapter between the TBU bearings and the framework – a solution that is also backward compatible.

“Our engineers have really approached this design challenge from the client’s needs and it will be exciting to follow the wagon evaluations that begin next winter,” says Fredrik Kangas, Managing Director at Kiruna Wagon.

The construction work will commence in April and after the summer the first of the two wagons will be on the tracks.

The two apparatus wagons designed for the Swedish Transport Administration will accommodate and transport electrical equipment.
