The Hornby Dublo Meccano A2 A3 Power Control Unit from 1956 is an original leaflet detailing the control system for model railways. This transformer, operating on AC power at 12V, is designed for Hornby enthusiasts looking to power their OO gauge trains with an analogue control system. As a pre-built unit, this model by Hornby is ready to go and is a valuable collectable for fans of model railways and trains.
