Swedish Railway Models – Diesel Units

Yd etc

In 1933, Hilding Carlsson delivered a drassine with 24 seats, really too large to be called a drassine, and so the Swedish railbus was born. Over the following four years, roundly 60 2-axle railbuses were delivered as type Yd, although somewhat modified from the original. They had a metal ‘skin’ over a timber frame. Very soon after, 2-axle goods trailers appeared, as well as bogie version of both types, and including passenger trailers and mixed trailers. They remained in service until displaced by the all-metal YCo6 family of railbuses.

  • NMJ has produced a limited ready to run model of the Yd, with or without trailer.
  • Perlmodell has produced a kit, mentioned here because it is a Perlmodell one that we have on the FLMJ! There are various other kits.


This is the Fiat designed railbus introduced at the end of the 1970s, that replaced all original Swedish designs. Construction was carried out in Italy and Sweden. Many have subsequently been exported.

  • Modellproduktion produced a plastic kit for the Y1, but it was without a chassis or running gear.
  • NMJ has produced models of the Y1 and YF1 in SJ liveries, and has said that there will be more, in an assortment of liveries. (DCC-fitted ones can be problematic, though!)
  • ONE:87 produced a limited edition high-specification (and price) model of the Y1.


The Danish IC3 in SJ traffic, the Y, was introduced in southern Sweden in 1990, and has been a successful design. One service also operated into Stockholm, where diesels are normally banned due to the levels of emissions – but the Y2 is very ‘clean.’

  • Heljan produced a poor quality model of the Y2 with a Tenshodo motor bogie. It was upgraded and improved with their newer mechanism. One of the AJF members has a latter set, and its performance is very good. However, it is not advisable to regularly uncouple the unit as there is a risk of damaging the electrical couplings!
  • Dekas has proposed a model of the Y2 in two liveries, original and current, for production in 2023.


Probably the most familiar sight on Swedish railways during the 1960s and 1970s, the ‘Y6’ is regarded as a quintessential design. Several were later sold to Denmark and Norway, and a derivative operated in Finland. Many have been preserved, others are used as works trains … they’re everywhere!

  • UGJ made kits of these (basic railbus and dual-purpose trailer), and there is an assortment of suitable chassis units to go with them.
  • Jeco has also made kits of these, for any suitable chassis unit, but more recently, they have made a ready-to-run version as Y6 or Y7, and with UB and UFV trailers.


Swedish railway companies deployed inspection cars to enable staff to keep an eye on the permanent way. Steering wheels were removed, and conventional road-going wheels replaced by railway wheels. Normally, they had a turntable that was winched down from the floor, lifting the car so it could be turned! The TGOJ owned a Volvo PV 831, which is now preserved.

  • Tekno Bygg made a very limited run of working H0 scale models of the TGOJ car – as a white-metal / brass kit.
