Route: Arosalinie Service: R1412, Arosa to Chur Issue: A red aspect is experienced at Untersax. When the aspect clears to green and the indicator shows clear for the right hand line, a SPAD error is displayed and the game ends when passing the signal board. Contacting the signaller returns 'Proceed as signals indicate' To pass this signal, you must wait 30+ seconds after the signal shows clear to proceed. Eventually, contacting the signaller displays 'proceed at restricted speed' and the signal board can be safely passed. The signal remains green / clear throughout.
