Choose from five versions of our Class 12 diesel shunter
Built exclusively for Model Rail by Heljan, the Class 12s deliver premium engineering throughout including a diecast metal chassis, powerful five‑pole motor, brass flywheel and high‑reduction gearing which combine to give exceptionally smooth, controlled slow‑speed running. Add a Next18 DCC interface and factory‑fitted speaker, and you’ve got a model that’s as capable as it is refined.
