This 1/4" scale model of the PRR FM class was scratchbuilt entirely from styrene. All of the rivets were impressed into the sheet material using a sewing machine (see my August,1975 MR article). The trucks are from Protoscale and are designed for P:48 exact scale. The lettering is from Champ. The closeup is of the PRR FM flat coupled to an upgraded Red Caboose NYC flat car. The cars have working AAR Type-E couplers from San Juan. The track was handlayed using Code 125 rail, tie plates, and rail joiners.
