Another possible cause for crashes in scenarios might be a memory overload, especially on 32bit computers that are near the min. system requirements of RW. Freight cars and locomotives are the most resource hungry items in the game, and using lots of them (and lots of different models) might cause the game to crash.
Especially when populating big yards like Barstow, try to avoid using too many different car models. Instead place some more colorful "eye candy" consists near where the player is expected to pass by, then fill (some of) the background sidings with long consists of only a few different car models. Seen from the cabview you won't notice a difference compared to having used tons of repaints to fill the distant yard tracks.
Another good choice for filling yards efficiently are my Low Poly Yard Filler Cars, available here in the file library or (a better detailed version) also part of the Portland Terminal route.
