> Redesigns Tramstation's Primary Tool Storage, also giving it proper
disposals.
## Why It's Good For The Game
Now the disposal bin in the Primary Tool Storage will be useable, and
looking nicer might encourage people to visit the room instead of the
Auxiliary Storage, which is closer to the rest of the station.
