Re: Why the big windows?

Back in the early 60's there was a bit of an epidemic of British drivers in France running off the road or into a tree, having apparently fallen asleep. It was eventually concluded that the constant flicker caused by the trees at the sides of the road could be close enough to a natural frequency in ...

Re: Joggled Stockrails

"My general point is this. In general terms - on the prototype, the switch rails, as they get thinner towards the tip, cannot take the weight of the vehicle and descend below rail level, and gauge level. On the 4mm scale model, the point at which the prototype cannot bear weight is the point at...

Re: Joggled Stockrails

I think it is true that joggles are relatively rarely, if atall, to be found on Scottish lines; perhaps this is true of some English lines also. The set is another matter, and is always necessary (unless your switch blades can taper to zero thickness). Certainly I have never used a joggle, and have ...

Re: early platform height?

There wasn't a standard, but many early platforms were much lower. This picture, taken about 1900, shows a station built in 1847. In this location, as in many others, the platform was raised later, but they couldn't raise the bit with the buildings on without unacceptable expense. There are still a ...

Re: The Burford Branch

Possibly a slightly niaive question. The big pipe is to let water out to the various columns; but where is the (presumably smaller) pipe to let water in? There might have been a pump, possibly steam driven.

Re: GWR Steam Railmotor Chassis

Very intrigued by your long 0.5mm drill. Evidently a long piece of steel rod; but how is the drill attached to it? Is that a collet on the end, or is there some other connection? It seems like the sort of thing I wouldn't need very often, but when I did need it I would need It badly. Allan F

Re: Bogie and pony wheel swing calculator

Then I worked out how much sideplay I could allow on the bogie, having first decided on how much I could narrow the frames ...

Re: Radius Testing - Practical Experiments.

Philip you are probably right -- I can't get up into the loft just now to measure it. But I think that, within reason, track gauge can be wider than standard on plain track with no harm done. But not through points and crossings. The only difficulty is trying to couple SWB wagons (and indeed pushing...

My tightest radius is 40 1/2 inches round the ends, and I found that 6 wheel locos could not reliably go round. However I relaid the curves using Exactoscale Gauge Widened trackbases, which give, ...

I saw these in use as couplings on an "O" gauge layout a while back. Very effective and seemed totally reliable as automatic couplers; but I couldn't work out how to uncouple them other than a fairly sharp tug.
