UP SD7 question

[Trainmaster.Curt]

Wow, those DD35X's or DD40X's are really Big *** locomotives! It'd be like comparing my girl's booty to a skinny runt of a SW1200RS

Here are some details on them-

Hey All

I was wondering when the UP SD7 was delivered whether they had silver trucks or black ones? Can anybody help me?

I did a search online but wasn't able to find many photos of the SD7s...
