PO-4

Five switchers worked out of Rigby Yard in South Portland, and up to five long distance trains departed from Rigby. Five long distance trains could also end here. PO-4 normally worked the evening shift starting on the west end of Rigby Yard and went to Yard 6 and Yard 8.

Symbols

PanAm used a four character symbol to refer to each train that could tell you where the train started from and where it ended up. Long distance trains got four letters, the first two for the origin, and the last two for the destination. Switchers got two letters a dash and a number. The nicknames used could confuse this though (Sappi-3 was actually SP-3, I believe). The OCS (Officer and Crew Special) was a passenger train used to reward employees for good service and give dispatchers, company officers, and prospective customers a look at the lines. It usually consisted of three former parlor service cars pulled by two FP9 locomotives built in 1954. And the Oil Extra was a train that ran as a stop-gap measure during the Lac-Mégantic accident and Montreal, Maine and Atlantic Railway bankruptcy and sale to the Central Maine and Quebec Railway.

I will list the symbols I know with their end point city or town.
