Hi there, RailWAM is an indepedent, custom piece of JavaScript documented here - w:c:dev:RailWAM. If you are having issues with it displaying properly on your community, I would suggest contacting the script authors or posting on the DEV Wiki forums. As it is a custom script, Fandom does not officially support it.
