Understanding the Sources & Destinations
It can be a bit tricky understanding the four letter source/destination codes. This should help you out both on the radio and on the internet.
MOAY - Mohawk Yard, NY - Ayer, MA
MOED - Mohawk Yard, NY - East Deerfield, MA
SEED - Selkirk, NY - East Deerfield, MA
EDMO - East Deerfield, MA - Mohawk Yard, NY
AYMO - Ayer, MA - Mohawk Yard, NY
EDRJ - East Deerfield, MA - Rotterdam JCT, NY
You can probably figure out that the four letters are really two groups of two. There are other combinations as well occasionally you may hear something with PO, that stands for Portland Maine.
