It looks to me as if the problem is simply level and alignment that you have anywhere with flex track and cork roadbed -- as you say, over time, it sinks, and often one side sinks more than the other, which means that many locos will derail at random. I would simply try prying up the part that's sunk and shimming it with pieces of cardboard, using trial and error until things work right again. The prototype has the same problem.
This is a big advantage, on the other hand, of using Kato Unitrack or similar -- with the rigid ballast base, it's more stable over time. It's worth pointing out too, though, that 6-axle diesels on local track would be under a severe speed restriction.
