those German designed locos are pretty cool and they were tough too ....I have seen Colorado historical photos of a Krauss going through Moffat tunnel here in Colorado ....that is basically a proving ground for rail equip where they starve for oxygen but still need a whole bunch of power to get up the grade...... its all a huge bottle of awesome.
Those Alco PA/FA still had that sleek look that just cant be beat :D:D:D
