Thats potentially reassuring, thanks, Simon.Any NMRA compliant decoder should work on any NMRA compliant system, (that’s pretty much all of them) though of course it needs to be capable of handling the motor stall current without damage.
Penny drops!a common wire to the rails at the nose, which is changed +/- by the switch.


Yes, in fairness the PMV instructions advise using resistance soldering, which I didn't, although most of my problems were solved once I started using phosphoric acid flux. The main problems were that the sides buckled when attaching the vertical framing, and if I was doing them again I would consider first soldering strips of metal angle to the inside faces as strengthener. New techniques may render such elaborate etched kits obsolete, but as you say, they look right, and it's hard to beat the crisp edges of metal framework. There are other G1 versions which don't look right at all!Thing is, Andrew, they look Right
In particular, the wheels look right, in a way that G1MRA Standard' ones never can.As for drag, they damned-well ought to slow down on a curve like that!
I'm seriously considering guard-railing my 2m radius one, not so much to keep the stock on, as to signal, "Yes I know this curve is tight!"On the solder front, my attempt to design a totally plug-and-play Resistance Soldering Unit has hit further snags.
However a home-build RSU is still within reach for anyone who can wire a mains plug - a separate conversation of course.(There's no significant cost saving in making one's own - it just avoids queuing for a small-batch commercial one.)

Memories like that stay with us a lifetime, and help to bring our models to life David - thanks for sharing. You were lucky to get one down the B&H as late as 1972. Although we lived many miles from their home ground, I saw a few as a child, and we had 806 Cambrian on a returning Motorail from a Devon holiday - leaning out of the leading droplight next to that big bulbous nose as we powered across the Somerset levels.Absolutely fabulous Andrew - the Warships were only around for the first seven years of my life, but they made a huge impression on me, both at home in the Thames Valley and on holiday in Devon. There was one wonderful afternoon in, I think, the summer of 1970 when my Dad took me on the train to Newton Abbot and we watched Swindon and NBL Warships moving around the shed and passing by on the main line all afternoon, and they were in pretty much all the possible livery permutations to add to the fun. My last trip behind one was in August 1972, when to my great delight Cockade‘s huge yellow nose appeared round the corner by Spur Junction and rolled into platform 4 at Reading to take us on holiday down the Berks and Hants to Dawlish. Your Druid is spot on in all respects - I am dead jealous!
