So, after buying MSB and driving around a bit that i noticed that the lights on plattforms are being turned on way too early. Combined with the sunlight the whole scenery and the train (when you're on the platform) looks odd. As you can see in the picture below it's 17:54 PM and lights are already turned on which is obviously too early. One should maybe turn on the lights at 19:00 PM or whenever its getting really dark. I dont know if its the same on the other routes, will investigate that later.
I assumed it was just a faulty photo sensor- those darn things are always failing in real life on my outside mercury vapor lights on my ranch
And if you play in winter / spring / autumn the lights go on way to late. If you have clouds and drive in the morning it pitch black and the all the lights are off and that for several hours. But that's a TSW core problem and happens in all DLC.
