Thank you Grahame. Newcomers might find an added single line description where it isn't obvious from the url. Possibly add mapping sites, especially one by a forum member and Railmap online.

 

Your suggestion is a good one. Categorising, a soundbite for each site, and some additions such as Railmap online are excellent thoughts.  I would be delighted if you were to add those one-liners; quote in a separate post and it can be moved up - the help would be appreciated.

The suggestion graphically illustrates the extra usefulness of having a little more than an alphabetic list of URLs ... for there is already a mapping site by a forum member listed at http://systemed.net/atlas/  . I suspect that's the one you mean ... it's the one I use by preference to look at network structure past and present. And others do too ... I sat opposite a teenager on a recent journey from Weymouth to Melksham and on his tablet he was tracking our journey;  I was impressed that he was using the Adlestrop map, and he was impressed that I was able to refer to it by name and "namedrop" the source.   And both of us were more than impressed by the clarity of the mapping and all the work that's gone into it.

 
Cut and paste job from what I know with a few additions. Hope it works.

Wow - that was quick and (yes) it does work.  I'm working towards a couple of end-of-year deadlines ... will give others a day or two to add further links and reformat (via a script) to help it tabulate.   Missing URLs that other folks rely on and love would be most welcome!

 

Better late than never?   Back to this ...

Probably too long a list in unsorted / uncategorised form ... other links and ideas welcome

 
Add

Replace

http://iris2.rail.co.uk/tiger/   Tiger – Source of station information

with
https://tiger.worldline.global/home

 

Thank you.  Updated (and a couple of others too)
* Other URLs remain the same but with updated / improved data such as the Adlestop Railway Atlas. 
* Some may longer be relevant / appropriate - please let me know
* There may well be significant things worth adding - again, please let me know

 
Updating the list ... adding and there may be others missing.   Also some of the below may be duplicates - I need to check back when home and not having to change trains at the next stop.
