7/14/87: Back in the day of interesting locomotives without ditchlights; SW7 cow and calf set 505/513 (blt. 9/50) head a transfer run into the East end of Clearing at Rockwell Street Yard. The cow and calf versions of SW7s are known as TR4s!
The J had some of those B units until the CN bought them out. So funny looking
That was old and unusual even in '87!
Sweet picture i love them. love end cab units. ^^ i believe i seen a pair of IBC units up for auction on Ebay well the slide of them.
That is what I cold old power!
I think they might still be working on the Minnesota Northern!
have you ever noticed that slugs like that look like steam engine tenders.
Now that you mention it...I see what you mean but the TR4B is a cabless switcher semi-permanently coupled to the mother unit and technically not a slug. There weren't a whole lot of these sets made.
Now they call them Mother and Slug.. Pretty cool step back into them days!
I miss those days, technically not a slug because the TR4B has a prime mover in it not just traction motors.
Nice rare unit.
