evangilder said:We have been chatting a bit about trains, so I thought I would start a thread for it. I am a big fan of the old steamers. So I will start this one off with the Union Pacific Big Boy. For your rail fans, this baby is HUGE. It's a 4-8-8-4.
It is one of 105 Challengers built for Union Pacific between 1936 and 1943 and is the only operating engine of its class in the world today
Wouldn't it be something to see that thing running?
JCS said:The UP sure had some intersting locos. Another besides the Big Boy and Challenger is the DDA4, the largest, most powerful diesel locomotive ever built, with two prime movers totalling 6600HP
I'll bet those 4 axle trucks can't be used just anywhere.
