Well, if you start the service 50244 on SKW (or even better in journey mode) the timetable tells you... 23:13 at Langenschwarz... well, I tried hard, but failed...actually, even when spawning on foot in Langenschwarz...well, at 23:13 no AI 50244 in sight...so,I waited and well... finally it arrived...the AI train with 14 minutes behind schedule (not taking the bad weather in journey mode in account)...well, I somehow lost my passion to wait for the train in KS-Wilhelmshöhe, but, I guess, 00:12 wouldn't even be doable by the AI train...
