Much the same drive design is in the B12/3 4-6-0; the K1 2-6-0 and 01 2-8-0, but with a single flywheel; the D16/3 4-4-0 and J50 0-6-0T without a flywheel: all of them very fine runners. (The D16/3 is of especial note, there's space that looks like Hornby planned a flywheel for this mechanism; and one could be added. It pulls very well for a 4-4-0 without traction tyres, easily the best Hornby have done in this difficult wheel arrangement by using a good mechanism layout and a metal boiler casting to maximise weight over the coupled wheels.muggins wrote:Do they use that mechanism on anything else?
In addition to the 700 class, the S15 4-6-0 has much the same drive with at least one flywheel, again good reports of its running though I have not yet had one before me to play with.
Enough of the temptation? Ho, ho, ho!
