OBU Hardware
Following the prototype OBU build for the WinterTrain v1 and v2, a second OBU was build. Even if the PBC was better planed, the whole OBU still takes up so much space, that it needs a separate waggon. A nice “circus” waggon was used for the new OBU.
In order to make the train set more flexible and easy to handle, a small plug was provided for the connecting cable between locomotive and waggon holding the OBU.
