Alco

An American locomotive works founded in 1901 by mixing 8 independent locomotive works together (kinda like conrail, except that's railroads). Made badass and sexy locomotives e.x the Big boy class, C-630m and RS-3.
Defunct in 1969 due to bankruptcy.

Railfan: Alcos may be clunkers and not so reliable, but that's what makes them loveable.

Alco

Alco is the kind of guy that lies a lot but will always have the back of his friends. He’s a guy you can have a good laugh with but also sometimes can be a bit annoying.

Alco is a cool guy
