Cowboy has the UP #9000 4-12-2's and is working on the UP FEF series (quite a task if'n you ask me).
His stuff, like TrainzItalia's, is DEFINITELY worth paying for!
Hey, while you're over on Italia's site, get the Huge Boy too. It can HAUL 9000T of coal from 0 to about 50-60 in close to 9 seconds! Even on a slight HILL!
