That reminds me.

Recently, I noted references to 'NLS' on the Coffee Shop forum which were clearly not related to the station code of my local railway stop.

I therefore expanded the definition of 'NLS' in our forum's Abbreviations and Acronyms page, at https://www.firstgreatwestern.info/acronyms.html , in the interest of clarity.

The National Library of Scotland is an absolutely brilliant resource, particularly for maps: I commend them to all of our members and readers.

CfNLS.

 
Looking at Plymouth and thinking that a lot of it developed quite late in the day and also, generally, 'How did this work'? Long distance Southern services - did they all start from Friary, tour the city and call at North Road and then Devonport before their onward journey? At... Catdown Bridge on the approach to Sutton Pool, did the Plymouth and Dartmoor Railway fade away and see its track lifted before the GWR reused the alignment and laid track once more? And at Laira, is that a flat crossing of the first on the scene P&DR across the GWR's line into Millbay Station?

Oh, and Albert Road crosses a good tunnel-over-tunnel intersection with little separation (with, for good measure a pub, the 'Railway Inn' sitting by the intersection and the location of surface buildings there very much constrained by the infrastructure beneath) . There's little indication of how the disused tunnel beneath the in-use railway is accessed for inspection. Perhaps there's an access between the two.
