4rail.net - Diesel Locomotives in Sweden

The class Td locomotives for the Green Cargo are rebuilt from the T44 locomotives by Bombardier. As with any diesel locomotive, many T44s were finally worn out and in the need to total rebuilding. Bombardier is in progress of rebuilding the units thoroughly, strengthening their structure and applying computerized controls. Probably the easiest way to distinguish between the two models is the running lights, see the difference above and below. Once you start looking there is a great number of smaller and larger differences, including the large smoke stack on the rebuilt units longer hood. As with any rebuilding programs, there has been extra work found by Bombardier compared with the estimates.

The class T44 are the backbone of the Green Cargo switching work. These diesel-electrics are both capable of handling just about any normal switching work and their numbers are large enough for availability anywhere. This class has seen a lot of action and many units will be rebuilt by Bombardier to class Td.

The T43 was for long another common locomotive to be seen besides the newer T44. Now the T43 at least fro Green Cargo (including the units of ex. TGOJ like in picture). will be phased out. Green Cargos wish to have fewer locomotive types is understandable and the T43s have by now reached already a pretty long lifecycle. Ecxpect to find these locosw on the third hand market, working on less demanding tasks than they currently are.

Monsters of the North, there are only 3 surviving units of the original ore loading / unloading T46 locomotives left. These formidable framed diesels are responsible about the yard operations at LKAB's yards on the larger mine sites like Kiruna and Svappavaara.

A few years ago there also was an attempt to rebuild number 2 of the locos to new condition while considerably improving the ergonomics. This ended up to bankruptcy of the company building the prototype and has left LKAB loco works responsible for the unit. This MTAB famous loco works in well staffed and equipped for this kind of work, so there is no problem managing to do the tasks necessary. As well as taking care of the aged original T46s.

Railcare in one of the operators taking care of the Swedish and Norwegian rail networks, but also occasional freight hauling. Most often, if you find this unit moving, it can be seen at the tip of the heavy MOW (Maintenance Of the Way) equipment. On the left, this locomotive was spotted in Abisco when during the Malmbanan total rebuilding in 2009. Picture by Ilkka Siissalo.

T68/Euro4000 is a rare sight even in Sweden, but maybe more common in the future. The loading gauge of Sweden allows the use of this latest design from the Spain, where this state of the art locomotive type is used in daily traffic to haul heavy intermodal freight trains. The Euro 4000 is also an interesting design for the builder Vossloh. Most of the other locomotive lines of the manufacturer are diesel-hydraulic. Also Most of the diesel-hydraulic locos will be long gone when this diesel-electric unit 901 is still at work 50 years from now. Look at the types Td, T44, TMY, TMX, all diesel-electric, old, and still well at work for a long time to the future!

26 units of class MZ were built for DSB (Danish State Railways) in 1960s and 1970s to retire the last surviving steam locomotives. After extensive use most of these locomotives were sold to second hand users in Sweden and Norway. Picture by Ilkka Siissalo 2009.

Looks like MTAB is using one unit for its ore switching operations and other services around Malmbana. Below left on the rainy day the T46 had had a fire in Svappavaara and TMZ 1413 was running for mine there to save the day for the heavy mining operations.

The resemblance of this TMYM with the American F-unit design in no coincidence. Nohab in Sweden built the units based on the proven American technologies. Although many have been rebuilt with different prime movers, the original attractive design, track motors, etc. just keep going year after year. Here a Svensk Tågkraft AB (STAB) TMYM number 1111 poses with a new paint and a new Cummins prime mover switched in Solna Sweden. The people around the locomotive were sad about the loss of the 567 sound. Pictures by John McKey, Hannu Peltola and Gerry Putz.
