I made some texture replacers for the metro maps used in-game to be actually useful.
I based these on the nice map from here: https://www.reddit.com/r/Fallout/comments/2kgml3/i_decided_to_map_the_underground_system_of/
I'm probably not going to work on it more, but if someone wants to edit them further, here's the file. It's giant, I'm not a good texturer :P .
