Pocket wagon

The name of these freight wagons comes from the fact that between the narrow longitudinal girders on the outside and also lengthways between the bogies, the so-called pockets are located, in which the wheels of the semi-trailers are particularly low.

For flexible use in CT, pocket wagons have hinged latches with ISO spigots on the solebar, so that containers and swap bodies up to 45 ft can be accommodated.

So that the loading gauge of the wagon is as small as possible, it is equipped with external side members that leave deep space for the chassis of the semi-trailer.

The semi-trailer is secured with its kingpin by a coupling plate or a saddle, which are located on a support frame; some of its wheels are still wedgelocked.

With regard to the service life of the king pin, loaded wagons are to be treated as caution items with 3 exclamation marks; a regulation that is also associated with a ban on kicking and walking.

Container support pins are usually present on the sidebar so that it can be freely used in CT trains and so that it does not necessarily have to be reloaded with a semi-trailer on the way back.

The T4.2, which was also procured by WASCOSA AG, has slightly cranked solebars on the pocket part for better accessibility of the crane contact point from lower semi-trailers.

The wagon has rising frames at the ends of the bogie and support beams with hinged latches for containers or swap bodies that can be moved at right angles over the longitudinal girder on rollers.

In the Great Belt Bridge rail accident, the kingpin of a semi-trailer had come loose due to wind pressure from the side and the trailer had been pushed into the clearance profile of the oncoming passenger train.
