That is an incredibly vague question. Here are some questions that would help enormously if you can answer them.
What bridge (what is its kuid number - names are too ambiguous)?
What version of Trainz are you using?
Define "werid"? (or do you mean "weird"?)
I note that this is your 8th posting in these forums but you still have not registered your copy of Trainz. Is there a reason for that? Click the Register link near the top of every forum page.
