A couple of times recently now I have had this phenomenon. Load a saved game only to find my viewpoint at the location where I left off, but my train has disappeared. First time was a few weeks ago on Pegnitz then again yesterday evening on one of the Chinese High Speed routes. I can’t offer any more technical insight than that, both were Career scenarios the Chinese save was a few weeks old but Pegnitz was from the previous day. Anyone else had this or suggest any possible user solutions?
