Just wondered if this is a bug or intentional. Running HRR in autumn with fog selected and I get this weird overcast sky, still prevailing at nearly 0700. In addition, the stations are all in darkness with the lights switched off as can be seen:
Another of the many issues in TSW - Environment lights are not controlled based on daylight, they are rather hardcoded to a specific time. Which then creates havoc in different seasons and light conditions of the year. So this on the screenshot would be perfectly fine on a clear Summer day, but not so much on an overcast Autumn morning.
It's not a bug, it's a poorly modeled feature. Unfortunately, there is no commercial incentive for DTG to ever rectify this. They still don't mind asking top dollars for this DLC though.
Okay, understood. Best to drive in summer or mid-day, then! Anyway the route is good, if a little short, another with two slightly different lines to travel over and some surprisingly steep gradients. I've even switched on PZB, now! Can't get enough of the German routes, hopefully one day we will get all the main routes from Zusi 2 in TSW!
