Keystone Details focuses on providing N Scale Pennsylvania Railroad specific detail parts for demanding model railroaders. We offer a wide range of models and model parts from accurate replacement sand domes for Bachmann PRR K4s to kits for PRR Plan 57984-B Tool Sheds. While we focus on N Scale PRR themed products, we also occasionally branch out into other roads, like our Erie Stillwell commuter coach kits (coming soon) and into other Modeling scales such as our S Scale PRR bumpers and G Scale tender truck sideframes.
