Have you turned it on? Yup, it needs to be turned on. Depending on the loco depends on the location of the system ON/OFF bi-selection switch. Id love to assist more but youve not provided specific detail on locomotive and platform..
Ahh ok. For specific ps4 cannot help. For GWE 166 aws isin fuse box on rear wall of cab. DSD is on wall above your head on left side looking forward. There is another warning system up there too. For the 66 and hst consult the manuals or hopefully someone else will chime in. Let me know if this helps you.
Have you thought of looking in the users' manual when a problem such as this arises? Granted, the manuals don't contain everything they ought, but you would have found the answer to your question there. Of course, they do reside only on line, but they can be downloaded to your computer. I don't know whether console users can access them or not . Ah! the heck with it: you were probably better off asking advice here.
Its not covered in the PS4 / XBox Manuals. The PC Manual has sections for the safety systems and other useful information. The Console Version manuals are missing those parts for whatever reason.
Why does that last train guy keep getting rude to people online? Allow it man, we all here playing the same game on whatever platform and should hence act as teammates. Save the mouth for real life, its a cowardly act.
