Graham Farish Class 101

[Geoff]

I have noticed on the bottom of the Class 101 there are 2 tiny dip switches on the drive unit and on the dummy, does anyone know what these control, as I am reluctant to try them when the loco is running spot on at the moment, it does not mention them on the service sheets.

Lights - on/off. So that if you run two sets of DMU's together you can switch of the red/whites in the middle.

Thanks for that Jack.
