Gaugemaster GM4210101 Network Rail Track Cleaning Vehicle.
This is the renowned Dapol Track Cleaning vehicle with a modern twist. It needs to be hauled by a locomotive as the often described ‘motorised’ element of this item reflects the motor driving the cleaning heads and not the movement of the model.
It works by the track cleaning vehicle supplying a small amount of cleaning fluid and then polishing the rails with the rotating pads. A full range of spares and fluids are available in the Dapol range. Please note that track cleaning fluid is not supplied with the model.
You can use the Hornby R8249 DCC decoder.
It measures 205mm (length) by 34mm (width) by 49mm (height).
