Carlisle, Newville & Western Road Power Part II

[icheymon]

Here are two more units I built for the old layout. Both are Athearn Blue Box SW1500's and both are powered by Helix Humper motors. I now use these as south end yard dogs and the 27 & 28 units as north end yard dogs. I added about an ounce and a half of weight in each and they pull very well.

One question I have is are MP-15's considered switchers? I have a couple of them I wanted to post and am not sure where I should put them.....Thanks

The Helix Humpers are very quiet, nearly Atlas level but a bit lower on speed, which is fine for my needs. I have a heard of them in use.......
