Hi Dave, Nice video and good to see the full extent of your layout. You have a steel? locking plate and slide bolt in the corner near the houses - is this home made or a bought in item. The reason I ask is I am looking for something similar to lock and align the lift out section on my layout. Keep ...

Some further work has resulted in the second line in the fiddle-yard getting wired and the two turnouts at the ends of the cassette roads being worked with servos. I've fitted these with 'Pocket money Kits' controllers from the MERG which cost only around £2.50 each. These just have a 12v input and ...

Hmm. I wouldn't put it past Apple to make the colour balance on the camera worse with each software release until you are forced to buy a new one. They already have been shown to make them get slower.

David

Thanks for that Keith, very useful.

Now, I can think about painting the lever frame to avoid concentrating on building the fiddle yard!

David

Hi John I'd seen the picture you mentioned, the large target on the gates is wonderful. Ultimately this is all a compromise and I'm pretty happy that I'm now getting close to something which I can live with. I'm not going to be able to extend the room by another 17 feet just to get more space for th...

Hi Noel In reality the level crossing was about 1/4 mile away from the river bridge. This meant that the gate keeper would have had a lever which locked the gates and 'the mangle' which pulled the slot off on the distant signal coming from Stoke and also on the distant arm on the Stoke bound starter...

And a revised diagram..



David

The photographs I show seem to show the pick-up goods either left on mainline or shunted into the siding at the front of the yard. The other side of the diamond was only a short cattle dock and not long enough to really be used as a head-shunt. Between points 10 and 11 sat the goods shed and I suspe...

so, for example
1 should be written as 'released by 2,3,4'
2 should be written as 'released by 5, locks 7'

Is that the right idea?

Thanks
David

Thanks Howard To your points.. I've corrected the 'distance' to 'distant'. The original arrangement was apparently a drum which had signal wire leading to the slot on distant 1 and the distant arm on signal 23. It was wound with a crank handle and locally referred to a 'a mangle'. The red lights and...

Thanks Keith

I'd wondered which way around the FPL would be. If it is more common for the points to normally be unlocked then I'll do it that way. Presumably the point only needs to be locked when signaled in the facing direction?

David

Hi All I've been making progress on my Stour Valley Dream, based on Clare and have drawn up a signalbox diagram based on the original on signalbox.org https://signalbox.org/diagrams/clare1933.jpg Because my frame is 'round the other way' I've decided to renumber the levers left to right to match the...

Hi David, No, it might look like that but the bridge isn't skew, there is just a slight gradient on the road over it. It is easier to see if you have the 'full colour' version at a decent size. IMG_0258a.jpg You still have the white sighting painted area behind the advanced starter. IMG_0259a.jpg Da...

And just to show the difference here are the two together with the brickwork drawn on.



And obviously any fool can spot the difference from a typically viewing distance.

Scalefour, Getting it, Alright?

David

Yep, managed to follow a better description online...

5-centre arch shown in red.



that's a new skill learnt..

David

In the absence of a 'decent practical geometry book' (like I suspect 99.9% of British households) I resorted to the internet. I tried drawing a 3-centre arch and that fits reasonably over the picture (green line) bridge1.jpg I'm afraid I got completely lost trying to follow the instructions for cons...

thanks everybody

I imported the picture into TurboCAD, reducing the colour depth to make it quick and easy but so I could still see the outline of the bridge. A combination of the digest pages, brick counting etc and I think I've got the right outline.

time for a mock up..

David

Hi folks Can anyone advice on how to work out (or whether there was a standard radius) what the arch of an overbridge might have been? I can see that there is obviously a different radius for the top of the arch than for the 'corners'. Would this have been an ellipse or two different radii? Prototyp...

Double Aahhhhhhh

Hence the question about radius and potential P4 layouts, as per another thread on here.
I'm dropping down to about 40" at the tightest spots, getting a continuous run in the room which is ~19'x9'

Unlikely to see a Pacific but a 4-6-0 is a possibility.

David

While I've been regularly posting on rmweb about the P4 layout I thought that those here who don't both with that site might like to see progress. I now have the five main baseboards which feature Clare station built and the track down and wired. This weekend I had fun playing trains and produced a ...

Yes those platform edging bricks were real beasts! IMG_6385.JPG I got the 3rd baseboard cut over the weekend and the cork underlay cut and marked up today. I've gone for making the underlay edge through the platform 20mm from the centre line, I reckon that should be about right. IMG_6431.JPG IMG_643...

Yes, that overhang is about 2-3 inches max.
The platforms have received some re-pointing post closure but are still basically original.

David

The digest 62.0 gives the minimum clearance rail centre to platform edge as 4'9" = 19mm. The digest also shows the current requirement for a 1' overhang on the platform edge. What was the deal with early platforms which were just vertical with no (or minimal) overhang? I'm trying to work out ho...

9 bells on the railcar

Perhaps making something like

would speed up the process?
