Many thanks to both Ron Jones and the National Railway Museum, who simultaneously sent me confirmation yesterday that the picture of the Railway office is indeed Crown Street! It will be interesting to have a look through Gore's and find the omnibus fares and try and do a bit more detective work on on the impact or not on the Square.
On an unrelated note I was at the Museum of Liverpool today and thought you may like a photo of the original wooden emblem from the first US Embassy which is housed there. The museum is well worth a visit anyway, but at the moment there's also a lovely picture of the Library in Abercromby Square as part of the L8 exhibit.
I'm afraid I didn't get to do a cemetery walk today, so no dead people updates, but I should have mentioned that last week i got a lovely facsimile copy of a book of views of the Liverpool Manchester Railway from 1831. The images in it can be seen here.
Sadly it still doesn't clear up whether the railway office picture is at Wapping or Crown Street, as different versions seem to state different things. I may have to contact the railway museum at York who hold the original sketches and see what they were called!
