The job was simple enough and required the DCC decoder removing and the track pickups and motor outputs disconnecting from the electronics PCB. I left the PCB in place so I could use the on-board switch to control the power, now supplied by a PP3 9v battery. I would rather have installed the battery internally but the only room for it was inside the area where the vac deposits anything collected eg loose ballast, scatter material etc. So I opted for external fitting which means it doesn't fit under my low bridge but that portion of track can be cleaned fully by accessing from both ends. I've left the coupling on at one end so it can be pulled or pushed by a loco or just pushed by hand.
Not the most elegant piece of rolling stock I own but it is after all just a tool (that only comes out the cupboard as needed) and works incredibly well.
