It's an indication of so many trains being in your viewing area that the total amount of polys in all the traincars combined exceeds the total amount of polys you computer can dedicate to the trains. Go to "options" on the startup menu and move the slider labelled "train poly count" (or something to that effect, can't check as I'm at school atm) further to the right. :wave:
Oh, my mistake, I should have specified, on the Trainz Startup menu (where you can choose Launch Trainz, Options, Manage Content, etc...) click "options". :wave:
