Re: Edington Junction

I haven't been able to see what advantage would be gained by rescaling a plan against the 6" ordnance map, as I would have thought that using the 6" to locate structures was even more open to the risk of rescaling errors because the scale is so much smaller than the 25" plan I used t...

Re: Edington Junction

Subsequently I rescaled the image within Templot so that the 500' shown on the printed rule corresponded with a 2000mm dimension on the Templot ruler. Hi John, You probably know that Templot can now import historic maps from the NLS web site and scale them to your model size automatically. Even if ...

Re: Exactoscale Products

Do people think that this puts C & L at risk? C&L was apparently viable and profitable under Brian Lewis, before there was any involvement with Exactoscale. So there is no obvious reason why it couldn't be again. There is still the entire copper-clad trackbuilding market, and 00/EM. The arr...

Re: Track Planning & Layout Ideas - New Builds Started

I have stripped Google and Duckduckgo as best I can with searches such as Furness Railway Track Plans / Signal Diagrams et al and only found a few. Hi Gavin, Why not look at the prototype plans? NLS now have most of the Furness area in their slippy georeferenced 25" map: http://maps.nls.uk/geo...

Re: Track Construction for a Test Track

At the cross sections B-B, C-C & D-D, it looks as though the head of the wing rails are planed on the running edge. Are we meant to be mimicking this when building P4 crossings? I cannot see any mention of this in the digests? Hi, It is the machining for the end flares. Bullhead wing rails and ...

Re: Track Construction for a Test Track

with wing rails I'm not sure but I suspect the crossing nose foot was left on and the wing rail foot planed off Hi Keith, Colin, That's correct. The foot remains intact on the vee rails and is removed on the wing rails as necessary. Here is a scan showing the cross-sections. BS-113A Inclined design...

Re: Turnout construction - Question here please.

Is there a P4 table to show the correct distance for each gradation e.g. 1 in 4, 1 in 5 etc? Hi Julian, You don't need a table. The distance from the FP intersection point to the centre of the knuckle is the flangeway gap multiplied by the crossing angle. So for a 1:8 turnout in P4, that is 0.67mm ...

Re: Turnout construction - Question here please.

One of the perhaps stranger aspects of this occurs with obtuse crossings in S4-X, where I have to choose "timbering as model" to get the timbering correct for exact scale track. Hi Tony, If that's the case it is a bug. The "as prototype" option should be exactly that. Just check...

Re: Turnout construction - Question here please.

Hi Julian, Here are some pics of an undercut switch. You can see from the shiny marks on the top of the blade that it starts to take some part of the wheel load at about the position of the second stretcher bar. Up until that point it is simply guiding the wheel flange, and is dull on top: undercut_...

Re: Turnout construction - Question here please.

If the knuckle is between two timbers it would be much easier to see the place where the bend should be once the timbers are stuck down onto the template. Prototype practice varied, I take it?

Hi Tony, +1 from me on your latest instalment. Never too old to learn. :) Using a rotating rivet to align the wing rails is a brilliant idea. I have never seen it mentioned anywhere before in 50 years track building. Certainly never thought of it myself. Making the flangeway adjustment after the rai...

Do the distances in the table scale down correctly for us in P4? Hi Julian, Which table? Generally prototype dimension can be scaled exactly for S4 (S4-X in Templot), but not always for P4.
