Many thanks to Pete for the EC and Malc for the GEA, Woodrow, woolybill1, Al, Ken, Ron for their UA very much appreciated.
Thanks also to everyone who commented.
During a 1.5 hour delay due to signaling failure on the east coast main line into Kings cross last Sunday, I had a chance to try and capture the new station concourse and great roof.
Hand held and the lighting has a large stop range too so not easy to control
Thanks for looking.
