An excellent piece of work. I think Neil has captured a lot of the atmosphere, although thankfully not the smoke!
Quite early on there is a view of Victoria Station, with the Walker's Croft Cemetery alongside. It's not a name I recognised, so looked it up. It brings up a page relating to the exhumation of bodies during alterations to to the station. The article says the cemetery was associated with the nearby workhouse, but maps of a similar period show that it was one of the graveyards for Manchester Collegiate church, now the cathedral, so not just paupers buried there.
Since there was a very limited space in the Collegiate Church precincts, and not exactly a lot of space around, it seems likely that tens of thousands of those burials mentioned in the registers would have been in Walker's Croft.
