The platform is just an object, and some of those routes are coded in RW. In BVE, you can't tell the difference. In OpenBVE, you can. RW, unless it has the command, will open the doors on both sides. If you convert an RW route to CSV using BRR, the doors will always open on the right (2 and A) Yes there is a way to fix it, you have to modify the .sta command.
