If you go to the B &M Group on Yahoo Groups, you will get plenty of answers-and yes they had names! I have several B&M Freight Train Symbol Books, that give the names, the official company names,not the crews "nicknames".
Some of the fast B&M Freights were continuations of MEC names. MEC's most famous fright was the "Morning Glory", an early AM fast frieght out of Bangor, for Rigby, with only a stop at Waterville-at least in the 1920's.
I have some of these Freight Train Symbol books, but they are temporarily stored in boxes in our garage, as we are redoing "my library room".
"The Maine Bullet" was a famous fast freight handled by the MEC,B&M and New Haven to NYC. The "Rocket" was a TOFC train, run by BAR,MEC and B&M, and continued for a while under Guilford. Guilford even officially called one freight, "The Press Runner", with ADVERTISED
48 hr. service from Maine paper mills, to publishers in the midwest!
Will try & dig the symbols books out in next couple of days.
Of course, the number of "unoffcial nicknames" was very long-and often funny-but usually "valid". Good example was "The Mortgage Payer", the Lowell to Hillsborough(NH) way freight that is written up in Neal's book, "
"High Green & Bark Peelers".
