I bought the new Hornby Duchess with digital sound and ran it with my Bachmann EZ-controller. I got all the functions to work except F9, the short whistle. I bought a Hornby Select controller but had the same problem so I telephoned Hornby customer service and asked for help. I was told that they could not speak for the Bachmann but that the Select only had 9 functions, F0 included, so that F9 would not work. Does anyone know of a way round this apart from buying another controller? It would be nice to erase the airpump function and replace it with the short whistle
