HO RND F7A Locomotive DCC-Ready PRR #9642 (RND-2237)

HO-scale EMD F7A diesel locomotive, DCC-ready, PRR road number 9642, from the Athearn Roundhouse line. Fully assembled and ready to run, this model brings classic mid-20th-century diesel power to your layout with authentic decoration and solid performance.

Based on Phase I EMD F7A tooling, the model features a revised heavy die-cast frame with room for 21-pin DCC decoders, flush-fitting cab glass, and improved all-wheel electrical pickup with two wires to each truck for reliable power. It offers single or dual headlights to match the prototype, separately-applied horns, dual rear coupler mounting options, and McHenry operating-scale knuckles. The drive system uses a 5-pole motor with precision flywheels and a multilink drive for smooth, quiet operation, while RP25-contoured wheels run on most track brands. Fully decorated and highly detailed, the locomotive arrives ready to run on 18-inch minimum-radius curves.
