OO Class 47s - The New Generation is Here!

The first batch of our superb new OO gauge Class 47 has been shipped from the factory and expected to arrive in the UK in February/March.

It’s many years since our old ‘OO’ Class 47 was last produced but the  time has come for a new generation to take over. Our most complex and sophisticated ‘OO’ model to date, it also marks the start of a new era for HELJAN UK models – they are the first to be offered with factory-fitted DCC sound across all liveries.

TEN liveries are available to order now, plus an exclusive Network SouthEast edition for the Gaugemaster Collection (see photo above) all with DCC Ready or DCC Sound options featuring class-leading sound by renowned expert Legomanbiffo. See below for the complete – and very extensive – specification that puts these models in a different league to our old Class 47. With a specification like this, these new ‘47s’ are worth shouting about!

All models have been produced in limited quantities and will not be repeated as we plan to produce regular batches of new ‘47s’ to exploit the full potential of the tooling suite over the coming years. Contact us now to secure your all-new Class 47s before they’re gone!
