Patrick Davey Posted March 18 Posted March 18 Two very random thoughts.... 1. The absence of loco crew is often commented upon in relation to modern diesel loco releases, and yes A/S do provide some of these as extras to be fitted by the user but what happens when the loco has to change direction.....could there be a mechanism devised whereby a driver is provided but hidden at each end of a typical dual-cabbed loco, then maybe with a DCC command, the relevant one can be raised? Crazy idea And.... 2. Does anyone actually make use of, or care about sprung buffers???? Quote

murrayec Posted March 18 Posted March 18 (edited) Fleishman I think it was did a loco with directional drivers, when one changed the loco direction the current driver flopped down sideways and the other guy flopped up at the other end! Eoin Just saw that link above! I found it here above while Googling which manufacture did it Edited March 18 by murrayec Google search 1 Quote

Sprung buffers are of little use with tension locks, Patrick, but with more ‘sophisticated’ coupling systems they can be quite important, as they actually absorb the shocks of train movements rather than letting the delicate couplings take the brunt. Can also be of use on curves etc. 1 Quote
Mol_PMB Posted March 18 Posted March 18 I’ve decided to use Kadees but I am mostly fitting sprung buffers. I’m hoping this will allow me to have visually closer buffer spacing as they can compress slightly on sharper curves. I have yet to see how well this works in practice! 2 1 Quote

Tullygrainey Posted March 18 Posted March 18 Regarding sprung buffers, I would echo the comments above. They can ease things on curves and prevent the derailing that can happen when rigid buffers clash. I fit my scratch builds with sprung buffers from Alan Gibson and always try to make them work. I've lost a lot of springs to the carpet monster though... 1 1 Quote
Warbonnet Posted March 18 Posted March 18 Sprung buffers cost no extra to do on a model either, despite what some other penny pinching manufacturers would have you believe 6 1 Quote
Patrick Davey Posted March 19 Author Posted March 19 (edited) Thanks all - I have learnt that something which I thought was a gimmick does in reality have a worthwhile function. Yet again this forum proves its worth! Edited March 19 by Patrick Davey 1 1 Quote
