Thanks Chris,
Well I tried it this morning and removed the body with out a problem did had you said with 4 small plastic scrapers just behind the rear wheel sets on both bogies then moved them a little near the tanks.
I reinserted the mounting screws in to the chassis and then slide the body off I didn't put it back on the plinth as the scrapers are to long but could cut them down.
The thing I noticed in side the wires are quite short that are used for the cab and domino lighting so will have to remember for when I DCC fit my chip.
I have gone for a Lez sliver plus 22 chip just waiting on rails now for that.
Thanks
Marcus
