Why this model matters

This Heljan railbus combines a faithful representation of a unique British Rail prototype with high-quality engineering and flexibility for both analogue DC and future DCC installation. Its detailed finish, lighting functions, and robust construction make it a compelling choice for OO gauge enthusiasts looking to add character and operational interest to their layouts.

How to use it

Place the locomotive on clean, 16.5 mm gauge track powered via a compatible DC controller for immediate operation. To run on a DCC system, fit a suitable 21-pin decoder before operation. Test lighting and drive on gentle curves first, and ensure track and wheel pickup are clean for smooth performance. Regularly check coupler fitment if coupling to other rolling stock.
