Why this model matters

The Heljan Class 15 D8242 captures the distinctive characteristics of the British Rail Class 15 diesel‑electric locomotive in early green livery with small yellow panels, complete with period‑correct seriffed numbers and double arrow logos. With all‑wheel pickup, smooth motor performance and DCC‑ready flexibility, it suits both traditional DC and modern digital control layouts.

How to use it

Place the ready‑to‑run locomotive on clean OO gauge track connected to a suitable controller for analogue DC operation. For digital control, install a compatible 8‑pin DCC decoder in the provided socket before connecting to a DCC system. Keep wheels and track clean for optimal electrical pickup, check couplings before running, and store the model safely when not in use to preserve its detailed finish and mechanical components.
