Swiss Safety Systems: ZSI-90, DP on the Arosalinie, part 1/2 (Train Sim World | tutorial)

Let's do the downhill tour from the mountain spa in Arosa to Chur station, this time in summer, while investigating the track magnet based safety system ZSI-90 that was in use on the Arosalinie until recently, as well as the deadman's pedal installed on the Ge 4/4 II locomotive of the Rhätische Bahn narrow gauge railway in Graubünden.

Full RhB passenger service from Arosa to Chur on the Ge 4/4 II electric locomotive in Rivet Games' Arosalinie DLC for Dovetail Games' Train Sim World 3, featuring short tutorials covering the safety systems used on the Ge 4/4 II RhB (36:13), the ZSI-90 system (40:40) and gradient signaling (57:35).

Also contained is a showcase of the stop on request signaling featured in the DLC.

My stream was automatically cut into two parts by Twitch.
