Just been browsing through Flickr to find that Tyne and Wear fire and rescue service have withdrawn their Dennis Dart SLF / ELC Spryte Mobile Command Unit (NK51XXC) and have replaced it with a Volvo truck based mobile command centre. The Dart had been new to the Fire service in 2001 replacing the Dennis Dominator based Mobile Command unit.

Can you share a link please?

I do have photos of said Dart but not online. However I went on the Internet and I found these.
