Balise reader

Planned improvement of balise reader:

TAG-reader antenna gets 6.7 V RMS 126 kHz sinus from the reader module.

Antenna:

  Area: 32 x 44 mm2
  Coil: 66 windings of wire ø 0.2 mm

Balise (TAG):

  Coil diameter: 20 mm

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.
