Your maps


Just a quick note to say that I'd like to move all your contributed maps into pages for each specific TD area you have covered (as with 'AN' page). This will allow all the info for a TD to be in one location and save people going through multiple links to find info & clean up the page.

Could you let me know if you have any objections? I'm about to start working on a big data release and am taking the opportunity to clean up as I start to get official documents, drawings & info uploaded.


Yes, this is my long intention to clean it up... Sounds great! --Jpl

Signalling Nomenclature


I see you have started to go through all the stuff uploaded so far :) hope your enjoying it. There should be some more on it's way soon!

Just a couple of things you might want to check 'L' is usually a Latch eg. LFENFIRE is the fire alarm state at London Fenchurch St, and L101TRS is TRTS for Signal 101. Latches are also used for things like shunter's acceptance/slot eg. L4001Y is a slot and LR1020Y is a release. Level crossings or anything else that is a latching i/o is generally a latch within the system.

Thank you for the clarification. 'L' is a Latch then. --Jpl

No problem - also watch out for the word 'off'. In the context of a signal it doesn't mean green. 'off' just means not 'on' (on being danger) off being anything other than danger. User:Q
