No technical reason to prevent the presence of different types of equipment in any given box. Incidentally, I'm highly impressed by your 3D printed frame, which seems to have turned out very well save for the loss of a handle on one of your 'spares' - can that be easily remedied? Yep, I noticed the...

The web site http://www.trainweb.org/singleline/stour_valley_line/stour_valley_line.htm shows two tokens for the sections of the Stour valley line for Clare. One is a Tyer number 6 token http://www.trainweb.org/singleline/stour_valley_line/cavendish_clare.jpg which is a large brass disk type token f...

I just managed to print off and paint a lever frame for my box. It took two goes to get the support structure right so that the levers came out straight but I think the result is not bad. This was printed on my Anycubic Photon at .05mm layer height. The route is set for a train from Clare to leave f...

I thought I'd post a few more pictures as I know not everyone here follows the updates on my rmweb blog. The first area of countryside now has its first layer of static grass on it. This needs a lot more work to get a variety of textures and colours but it is coming on. IMG_7004a.jpg I made the firs...

While in Penzance last week I was reading the Oakwood Press book on the West Cornwall railway. I was somewhat phased by the description of certain coaches as being made of wood and Papier Mache (This would be ~1850). How and where did you make a prototype coach out of Papier Mache?

I thought folks might like to see my progress with product I'd not come across before. Model Scenery Supplies sell a packet of tree armatures under the brand name 'Footpath'. These seemed good value to me at £9.85 for 5 armatures about 140mm tall. As supplied they are a little squashed together in t...

I'm trying to work out how to route the point rodding on my layout based on Clare in Suffolk. Photographs only help a bit but I can see a run of rodding down the signalbox side of the tracks only. The photographs I have show this on the original track arrangement which had a siding and kick-back whi...

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?

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...
