Re: Producing accurate track plans from photos - practical?

My track-gimping page is also at: http://templot.com/companion/index.html?info_files_gimp_track.htm The GIMP pages are actually the most viewed on the Templot web site. They have remained unchanged for 10 years and are due for an update. You might find The GIMP a strange program to use. It scatters ...

Switch and wheel diagrams in RAIB report

The RAIB accident report released today includes some interesting diagrams of switches, switch rail planing and wheel profiles:

Hi Howard,

There is a currently-running topic (now up to 7 pages) about the Minories track plan and the operating practices of such termini here:

Re: Turnout troubles...

Hi John, I think you have the blade tip too far forward (at B in Allan's diagram). Prototypically the tip should always be supported on a slide chair, not hanging in fresh air between the timbers. And practically, if you do that so that the tip is forward of the set in the stock rail, it will be imp...

Re: Tracklaying onto Templot print outs

For a large plan it is very difficult to handle and stick down long rolls of paper. It's often easier (and less expensive) to use individual pages printed in Templot and trimmed to the red lines. This is about 100 times easier if instead of printing on ordinary 80gsm office paper, you print on somet...

Re: Knuckles's Turnout Construction Log

I joined up the check rails, but the relative positions of the 2 turnouts made this more inevitable than in your case. Hi AM, In that case you may need to check that you have a full 6ft way between the outer tracks. If this spacing dimension is less than 44.67mm (which is probably the case in this ...

Re: Midland Railway track templates

Slaters do what they call a Track manual. Might be worth contacting them to find out what is in it. Very little that will be new to P4 modellers. A turnout is referred to as a "point" throughout, so you can judge for yourself the level at which it is written. 30 photocopied pages with a l...

Re: Triangular gauge use in building pointwork.

So, on plain track, which would normally only have a check rail on the inside of the curve, the check rail is placed to dimension A from the far running rail (outside of the curve) and the distance from the nearest (inside)running rail can be widened as required by using special chairs, if I unders...

Re: Triangular gauge use in building pointwork.

when you apply Martins comment 'Nothing ever has a wider check gauge' to check railed curves it doesnt appear that such a piece of track could actually work. Hi Jim, I don't understand your problem. If it wasn't important to maintain the check gauge at 4'-6.3/4" in all circumstances, the railw...

Re: Triangular gauge use in building pointwork.

It seems to me that Jim is referring to checked curved plain track whilst Martin is talking about the dimension for the all important check gauge at the crossing on a turnout. Hi Wally, The check gauge is the same for both. On gauge-widened plain track, the check rail flangeway is increased accordi...

Yes I am sure Jim. I have edited my previous post to include a diagram. A is fixed. D is don't care (C minus A). Special check rail chairs are used on gauge-widened curves to allow D to be wider than normal (by the same amount as the gauge-widening).

Re: Triangular gauge use in building pointwork.

Hi Jim, Prototype pointwork was rarely curved sharply enough to need gauge widening, and where it was so curved it was usually in yard areas used only by 4-wheel wagons and short-wheelbase shunting locomotives, which don't generally need gauge-widening. Nevertheless, where gauge-widening was needed ...

Re: Triangular gauge use in building pointwork.

The issue with prototype track is that the check rails are spaced from the stock rails using spacer blocks - these ensure that the FLANGE WAY remains constant, fixed and immovable. Therefore, if gauge widening is introduced, then the CHECK GAUGE becomes incorrect. Since the most important dimension...

Liquid 2-part polyester resin was then carefully brushed around the two sleepers. This soaked into and ...
