Really great, Simrail.
Went on EN4, took over a freight on the southern route heading for Katowice. Managed to drive about 3km before being brought to a stand at a red signal alongside a passenger in the same direction. Signal box ahead controlled by a player, perusing the interactive map looks like he had just stopped all the trains so the AI controlling where I stood couldn't call a route forward for either my train or the AI.
Which is why MP is a lottery and yes you could get a good run, but I just wasted 30 minutes going nowhere which could have been spent more productively elsewhere. Which is why SimRail desperately needs the MP equivalent game available in SP (along with the ability to save of course).
And no one is saying TSW or TSC is perfect, they ain't. But SimRail is not the Holy Grail some thought it would be either.
