Well SteveM6 That did not work. The Elite seemed happy enough programming the loco, but it remains stubbornly dead. Fortunately, switching back to HM7000 it still works- no damage done. (p.s I have so far programmed over 20 dcc locos with 100% success in case someone suggests that I am doing that bit wrong). Any further tips, however small and obvious, please let me know. It must be something simple that I am missing.
