I have not yet purchased a 56, but have been reading the above comments with interest. As I am used to the superb running qualities of American models, I am a bit wary of buying something which has a motor bogie, instead of a "proper" drive system - central motor with two flywheels, cardan shafts to both bogies with all wheels driven, and no traction tyres.
I have a Bachmann class 66 which is quite superb and virtually silent in operation. Oh, for a 56 with that quality!
Is there a motor bogie available which could be used in a 56 (maybe two bogies)? This should give lots of power and much better running.
I did hear a rumour that Hornby may do a 56 with the quality of the new class 60. If true, it would be worth the wait.
