Do they have a vendor that sells the game MEXICAN TRAIN with numbers on it. Also the racks for the tiles to line up on.

I think you'll find what you're looking for at Arizona Styles Games at the very south end of the first row, A-1.

I have seen the game but not sure about the numbers. What I can say is the market has almost every thing a person could want.

Yes

Yes there are alot of vendors with all the things that you need for Mexican train. Most are the same price to.
