Do they? (Genuine question) My understanding is that (DC) motors develop their maximum torque at low rpm due to the back emf in the winding increasing with speed which opposes the supply voltage, reducing the current... It's entirely possible that I am misunderstanding. Best Scott.

Good point, although I don't think the Navy's anti-submarine nor anti-surface warfare machines are included within that, nor the training helicopters; just the commando helicopters from the senior service? Best Scott.

It is a Merlin, but is most likely a Royal Navy example. Best Scott.

Five volunteers SUSPENDED from NYMR
scottystitch replied to 6990WitherslackHall's topic in Preservation
I was about to reply that it has nothing to do with being volunteer railway organisations, and exists across the whole of society because...(some) people. In a previous life I was made unwelcome because I had a degree. The question that was posed constantly, you know...'banter', was 'so do you think you're better than us?' Best Scott.- 906 replies

A distillery a mere 5 miles from one’s abode; enjoy! Best Scott. -
Looks great. The hardest step is the first step, and you've taken it. Good job! Keep at it, in small chunks, and it will all come together. Best Scott.

Co-incidentally, I was at Beamish yesterday, and in the Rowley signal box there are at least two levers allocated to ‘wedges’. My understanding is that these are what is referred to above. One was on the coal drop siding. The ‘signalman’ was explaining to some visitors that these ‘derailed a wagon if it rolled down the coal drop road toward the running line, similar to the result of a trap point’ i didn’t see the wedges themselves, just the levers. best Scott.

There's a possibility that this could be another one?: This image here from 1975 appears to show some discoloration to the connected door plate, as if had had a repaint?: -
Edinburgh Haymarket and Exeter St. Davids.
scottystitch replied to Mike-H's topic in Modelling real locations
Take a look at Aberdeen Kirkhill, perhaps it might inspire. This is a carriage/motive power stabling/servicing location with a twin track mainline running past. It is 4mm scale on OO gauge track It is 29ft by 10ft in 4mm/OO, so circa 15ft by 5ft in 2mm/N Best Scott
