I had thought about using 51 and if we do we will have to "load light and go often", as my grandfather used to say, since it is all downgrade from the height of land at Alna Center to the EOT. Slow running and a strong brakeman will be essential. We'll also have to get the loader run up to AC for loading cars. Both of 118's couplers are slotted and one of 126's.
First order of business will be replanking Sheepscot Mills crossing.
