locked Re: Early Diesel switcher assignments

Try a thru freight with a pair of F-7s back-to-back followed by three SW1500s on a 150 car train . . .

That would be a sight to behold for sure. I’ve always thought an F7-GP38 pair looked odd but the idea of F7-SW1500 would be great. One for the layout for sure.

Here’s another advantage to those SW1500s being delivered on Flexicoil trucks: they could be used as road power in a pinch. When I was in Southern’s training program in Greensboro 1971-1972, many of the Alco and older EMD switchers were retired and replaced with SW1500s. Some of these assignments were at outlying points and only worked Monday-Friday. 

In the meantime, yards accumulated freight during the week that exceeded what could be moved on scheduled trains, so Southern would operate clean-up extras on the weekends. On, say, Friday evenings, one of the lesser freights would gather up SW1500s and take them to, maybe, Monroe or Spencer, where they would be put to work on main line drag freights, mixed in with regular freight motive power. They would work on drags over the weekend and would be redistributed to their assigned locations before starting time on Monday morning. At 1500 hp, they were the equivalent of an F7 and were frequently mated with F-units on the drags. The disadvantages were that the SW1500s did not have dynamic brakes nor did the cabs have some of the creature comforts of F-units or GPs, so I never saw one in the lead, but they made dandy boosters. And I’m not aware that they were restricted speed-wise - they were good for 60 mph. 

No, I never took a picture of one of these main line trains with SW1500s. Yes, I am kicking myself.

I don’t know (see my posting just now) but I suspect that particular roller bearing equipped switcher allowed Southern to close, or cut back, operations at the Alex disel shop.

I grew up in Arlington and started hanging out at the Northern Virginia Model Railroaders layout in the old Alexandria yard office about 1971.  IIRC SW1500 2300 was the usual yard engine that I remember working there at least until I left for college in 1974.

Good study.  I assume the $35k operating savings is the steam maintenance costs vs diesel maintenance.  That’s alot of steam
maintenance!  But all of our steam was at least 20 years old by that time so no wonder.

I grew up in Alexandria, Va and I don’t remember seeing any true yard switcher after about 1970.  Is there a system level record of switcher assignments for that time period?
