About this model

OS-Railway is a complete system of track, trains and accessories, all designed to be fully 3D-printable. The size is the same as O-scale (32mm track) but printability is prioritized over scale. Update!! Now gearbox available for 24mm DC-motors! This page covers the Z70 locomotive, for track pieces see a separate page Klick here for track: Klick here for cars: This locomotive was inspired by the Swedish lokomotor Z70 but the dimensions are not strict, the wheel base has been shortened to assure that the train can cope with the rather short radius of 300mm used in my track and switch design. The body has been sculpted to pictures so it is not perfect scale either. The aim was to create a easy-to-print locomotive that looks OK, but not a super complicated set with tons of parts. The kit inclu…
