| GM&O GP30 524 in the dead line at Paducah, Kentucky on June 25, 1986, photo by Chuck Zeiler. This locomotive was built in September 1963 (c/n 28426) on EMD Order 7666 and was eventually rebuilt into CSX road slug 2254. Stencilled under the cab window are the words: ISELIN SHOP. It is riding on trade-in trucks from Alco FA1's, generally referred to as AAR Type B truck, although it appears that that term originated at Alco, not the AAR. A more correct term might be GSC Type B truck, since the design originated with General Steel Castings, a foundry jointly owned by Alco and Baldwin. Quoting from the Alco-GE Locomotive Specifications for the 1600 HP A unit, Section 3-Trucks : TYPE - Two four-wheel, swivel, swing motion, pedestal type motor trucks applied. CONSTRUCTION - Cast steel construction. Frame is spring supported on two equalizers on each side, with triple coil springs between the equalizers and the frame. Triple elliptic springs are applied between bolster and spring plank. Center plate safety locks applied. AXLES - Two (2) axles, of forged open hearth steel, per truck. WHEELS - Four (4) rolled wheels, 40" diameter, per truck, to A.A.R Specification M-107-48, Class "B". |
