The link above is to the BBC web site. The article is all about closed major railway stations that have all but disappeared. Both the former Liverpool Central and Liverpool Exchange Stations are included and there are some historic photos.
I published 3 photo’s of the old Exchange Station on my Flickr site only a few days ago, being unaware that John Dodd would point me to this BBC article soon after. This is the link to one of the 3 photo’s I published:-
You can see the other two photos (all 3 are from the National Railway Museum collection) by scrolling to the left when you are on my Flickr site.
