I'm busy buying stock to give me the option to switch my layout from the early 60's to the early 70's so that I can 'ring the changes' in about an hour. I'd really like a Class 31 in blue but think the only one that's available is the Hornby Railroad version and just want to be sure that it's smooth runner and not of the coffee grinder motor ilk of some earlier Hornby offerings. I'd be grateful for any views that owners of this loco might have.
