Tangent Scale Models is proud to offer our 33″ “semi-scale” Tread (.088″) CNC-machined blackened brass wheelsets for our power-pickup caboose trucks. These are the only solution for those who want to replace their current “standard tread” wheels with wheels that are more narrow in appearance. These wheels operate well over normal track, so don’t be afraid to upgrade the appearance of your Tangent Cabooses! Tangent wheels are leaders in quality in HO scale. These specific wheels are offered in convenient 4-axle packs, the perfect amount to upgrade a single caboose. PLEASE NOTE: Tangent “Needlepoint 1.004” wheelsets DO NOT WORK in our caboose trucks.
