I have notice when you operate any of these trains at night the headlights doesn't shine on track only when you use exterior camera but in cab you can't see any posting along the track
Voted ‘thanks’ for showcasing the exact reason polls need to go. To answer your question though, AFAIK the signage on HSC is not reflective, as it’s a TSW 2 route & hasn’t been upgraded to include the reflective signage. Coupled with headlights being poorly implemented overall, you basically get no nighttime visibility.
