Question for the technical people/pway Inclined or Vertical

[Alex Neia]

1) If you found yourself standing in front of a crossing with nothing but a measuring tape and chalk and was asked “is the crossing your looking at inclined or vertical” then what sort of checks or things would you look for or do to determine if the crossing was inclined or vertical?

2) Where is all the literature/information regarding standard geometry for inclined switches and crossings? There seems to be a considerable amount of information regarding vertical S&C such as the track design manual but there is nothing for inclined S&C. I have found that there are no tables that I can look up for inclined geometry that will enable me to check what the design lead length is or what the correct nose to nose should be etc. Is there anyone out there know of or can point me in the direction of detailed information for inclined S&C. Sometimes it feels like a mass conspiracy to conceal any information on inclined geometry WHY?

Thanks

Have you tried British Rail track books? Their textbooks are incredibly technical, i am afraid i am not experienced to help.

Bull Head and CEN60 layouts are all inclined.
98lb, 109lb and 113lb rail leads will also be inclined.

So you only have a choice for 110A and 113A/CEN56 layouts.

Vertical baseplates all have the letter V in their numbers, no V and you have an inclined layout.

As for details how about the REPW drawings?


Also inclined S&C tends to use the older ST and Kinetra clips, and is less likely to be strengthened.

If you look at the plain rail just off the switches or the back of the nose. (Unless in a follow on case with Vertical plain line between S+C)
You be able to identify the location of the Twist rails.
The actual twist may be hard to spot but the presence of a change from normal inclined baseplates to V baseplates gives an indication of which bay the twist may be in.
(Unless somebody forgot to install a V baseplate as has been known)

Or the twist rails were either never fitted, or have since been removed by over enthusiastic re-railing.

What was the point of quoting the question?

It is not my intention to be critical (or personal) - it happens so often on this forum and I simply don't know why this should be. And I mean the quoting happens often, not my being critical (but it probably does)!
