I was wondering if its even possible to start the 465 from cold and dark, I cant find the AUX Power, and their´s apparently no manual?
Look to your left, the panel under the safety systems you will see a button with aux heat and lights, hold this for 15 seconds and the train should power up. Note the master key needs to be on before doing so.
Also here is the TSW3 manual: https://cdn.akamai.steamstatic.com/steam/apps/1944790/manuals/TSW3_Manual_V1.0_ENG.pdf?t=1662485149
