Wm. K. Walthers, Inc. has been the largest model railroad distributor in North America since 1932, headquartered in Milwaukee, Wisconsin. Walthers produces its own product lines — Mainline (mid-range value), Proto (premium detail) and Cornerstone (the gold standard for North American structure kits) — and also distributes effectively every other major brand in the hobby.
Our Walthers collection focuses on their HO Scale wheelset and detail parts line: 33" Turned Metal RP-25 Wheelsets with metal axles (2300) and plastic axles (2301), 36" Turned Metal RP-25 Wheelsets with metal axles (2302) and plastic axles (2303), and the 584408 Replacement Geared Driver Assembly (diesel wheelset, 2pc pack). Walthers metal wheelsets are the industry standard for replacing plastic wheels on stock rolling stock — they roll farther, stay cleaner, and reduce track gunk dramatically.
This is a small curated selection from the full Walthers catalogue — contact us if you're looking for a specific Walthers Cornerstone structure kit, Proto locomotive, or Mainline freight car, and we can source it through our distributor network. Pair Walthers wheelsets with Kadee for couplers and trucks, and InterMountain for additional wheelset options. Ships from Oakville, Ontario. Free shipping on orders over $250.
