People who break the rules of the New York City Transit Authority for their own benefit. This is usually illegal, as it involves stealing
MTA property, and/or trespassing. This includes breaking into the
cabs of subway trains, peeling stickers off of buses, or changing
the route signage on trains without permission. It also often causes confusion in the system.
Conquesters don't usually admit their wrongdoings, and usually claim to be "civilized transit enthusiasts."
Example:
Foamer: *removes poster from
subway station for an active service change*
Railfan: OMFG YOU
CONQUESTER! WHY WOULD YOU STEAL THE POSTER!?!
Foamer: It's for the collection. Now leave me alone, since I'm just trying to enjoy the trains and I don't need your ass annoying me.
