Two Unit Fairbank Morse Diesel Pulling Around Lead, East End of Lambert's Point Main Coal Yard, 1960

NW Units 129 and 142. Shows two Fairbanks Morse units pulling coal cars around one of the lead tracks at the east end of the Lambert's Point main coal yard. These multiple units, which are about 112 feet in overall length, are used in classifying trains having as many as 100 coal cars. Because of the length of the trains, the ground crew at the rear end of the train cannot be seen at all times form the cab. In order to permit signal passing from one end of the train to the other, the carrier has supplied the conductor with switching lights. These switching lights, which the conductor sets up on a stand about the height of a switch stand, are not always within the engineer's view, because of curvatures, and it is frequently necessary for the aspect of the switch lights to be relayed from the fireman to the engineer.
