<{POST_SNAPBACK}>I do not think that with the Twin Centre there is any danger of changing the addresses of all locos. I have never used a TC, but I have an Uhlenbrock Intellibox which is largely identical (and information on the Fleischmann website shows that main track programming is the same for the TC). I assume that you are using a DCC rather than a FMZ decoder. Put the TC into programming mode, go to DCC programming, go through the various programming methods with the down arrow till you come to main track programming. You then have to put in the decoder's current address, after which only the loco with that address will be programmed. Then you simply change CV1 to the address that you want.
Thank you for your help but I still cannot get it to function. I got to CV1 then after the = sign put in 2 plus the return key, this got me an OK on the line above but leaving the program didn't result in the loco recognising its new address, it firmly remains 3!
