I have now received my SELECT controller back from Hornby having had the firmware updated. Maude now runs fine - address 03. The 0-6-0 loco that I originally had as 03 now runs as 01. This loco was the one i set up an acceleration value for which now seems to be very slow. Am I correct in thinkibng I can change this but must use a CV address - which was not available, so not any experience yet, on my original select version. Thanks for your help
