Denmark - S-tog commuter trains of Copenhagen
For a full scale picture, please click on the picture shown !
Currently all the København commuter trains, the so called S-tog,
are of one and the same type. The fourth generation of S-tog trains are of the class SA (8 coaches) or its
shortened variant class SE (4 coaches). They are wider than normal
trains, but their coaches are very short. There are only individual axles instead of full bogies placed under
the junctions of coaches. All these features make these trains quite special and also well suited for large
numbers of passengers
quickly moving in and out. The first ones of these trains were built by Alstom and Siemens in 1996 in Germany, after which
Adtranz and Bombardier built more of them in Randers, Denmark 1999-2006.

A detail of the same train as above. Driving these trains in the 1930s was still done while standing and was quite a
different job from what it is today.

Some of the second generation S-tog trains were still in use in 2004 when Sanna Siissalo took this picture at
København central station 20.4.2004. There was at a certain time quite a scandal, as it was found out that these trains
contained asbestos in such a manner that passengers and personnel could have been for years inhaling asbestos particles.
This picture was taken in 1996 as the S-trains of the new 4th generation had not yet even entered service. Two units were
used for tests and driver training. The car body is very wide indeed, and some work had to be done to the infrastructure to
accommodate the extra width.

S-trains of the new 4th generation run on single axle bogies controlled
by hydralic cylinders. In normal service the mechanism is covered by panels.

Already well before the time of the S-togs, commuter traffic around København was crowded. DSB built a large number, up to 60
coaches, of these doubledeckers until 1901. They were not at all popular as they were small and crowded and as the technology of
the time made them to swing from side to side like ships in high seas in a nasty manner. They soon got a nickname "Bismarck",
referring to the famous German chancellor and arch enemy of Denmark.
