This RailRoad Class 66 diesel was built for freight trains and operates across the UK making it the perfect locomotive for your model freight train. It is compatible with many wagons from Hornby. It comes DCC-ready with a 21-pin plug, meaning it can be upgraded to run on DCC or with our HM7000 Bluetooth-controlled system, which also includes sound via a speaker inside the locomotive.This GBRf-owned locomotive is finished in the attractive turquoise, blue and silver colours of Aggregate Industries, at whose quarry at Bardon Hill it was named ˜Sence in July 2015. The name refers to the River Sence which has its source just north of the quarry.
