Re: Preventing rust on steel rail

Bit of a concern. I have track made with steel rail - over 30 years old, abandoned in a garage - no rust.

Technique or storage?

Re: Alan Gibson Loco axles

I remember buying lengths of axle from Mike Sharman, it was beautiful stuff to turn. He said it had a high lead content.

Re: Alan Gibson Loco axles

The thing to note is that some axles sold by the trade are not 1/8" - 0.125".

Also not all supposed 1/8" reamers are actually 1/8".

Plus there is 1/8" clear.

I have a 1/8" taper and parallel (Dormer) reamer for bearings.

Re: Signal box diagram for Rospeath Lane

14 could be one of those signals normally left off, otherwise the signalman would forever be pulling it on and off for every move, they are though unusual. Hence I don't think it would have been there.

Re: Signal box diagram for Rospeath Lane

I think I would drop disc 14, no need for it. Ringed arm 4 should be a disc.

Agree on the numbering on the bracket. Presume 18 would be a 3' arm?

Here is an older style of digram.

Re: Signal box diagram for Rospeath Lane

Missed this post, sorry Tim. I think I have read somewhere of empty coal wagons being propelled down the coaling stage slope under gravity with pinned down brakes. Must see if I can find it again as I like your suggestion of the headshunt being on a slope. Me thinks this would make a nice project t...

Re: Signal box diagram for Rospeath Lane

That could be done by a few choice gradients, if the reception road (for example) was on a rising gradient, the wagons would just roll past the engine. By the way I'm not saying this is what would have been done. I've seen yards which were entirely worked by gravity, locos just delivered and collect...

Re: Signal box diagram for Rospeath Lane

The unusual bit is the double disc. Taking Melksham, 31 for 30 reads to down main or siding. Not a double disc. Limpley Stoke 23 reads to down goods running loop and down siding, again not a double disc. Remember, GWR practice would be for a white light instead of a red light in ground discs. This c...

I wouldn't expect a route the wrong direction on the Up main. Here is Melksham, sorry it's in B&W.

Re: Signal box diagram for Rospeath Lane

Standard GWR practice would see 15/20 as a crossover, with 20/24 as another crossover. But FPL 25? Not needed. And where are the two routes 13/14? I can only see one route there into the yard. If you were pulling 13 off to run along the up main, where is the next signal? Not sure about bracket 4/6, ...

Re: Gibson Crankpin slop

A known problem. You will never get reliable running with sloppy bushes(!).

Options:
1. Wrap PTFE tape around the pins.
2. Try another make of crankpins.
3. (my method, but I do have a lathe) make your own!

Re: Tim V's workbench - latest shenanigans

They actually aren't that tight, you need to be able to slide the pegs up and down. It's the flex in the upright pole that gives the friction. Give it a go - the materials are virtually free!

Re: Small hut at Swanage MPD

The picture in 'Swanage railway in colour' is a bit more straight on. The door is full height - which would imply it's not a toilet. I would expect to see the door have gaps top and bottom for ventilation!
