It will be very interesting to see how the models evolved both from the outside and their internals. What would really put the icing on the cake is a discussion why certain internal changes were made and what was their hoped for advantage.
Bachmann Class 20
I will be using this in a forthcoming review. I must say that it is a fantastic model. Runs very well and is solid and strong. Perfect for hauling rolling stock around any layout.
As I don't know much about these Class 20 locos. Can anyone please tell me something about them? There are versions with disks and versions with head-boxes. When doubled-up, were the disk locos and head box locos ever mixed? Were they from different periods? Were head-boxes added to the disk versions to upgrade them?
