It shows what Lima could have offered the UK customer. They had all the necessary know how in the group to produce the centre motor driving both bogies mechanism layout, of which the class 20 is 'half full'.brammie wrote:... Lima of some age, but excellent runner...
It's a very strange set up on the Lima 20 BTW. Reduction is only 4:1, so it would go a scale 400mph if unrestrained. The restraint is provided by the pick ups on the unpowered bogie acting as brakes; these pick ups are metal sheet resting in a U channel on the wheelbacks and are very draggy. So draggy that without traction tyres the powered bogie can barely move the model!
Never having seen Hornby's version of the Lima class 20, I don't know if they have simply replicated the Lima arrangements?
