the mail train

went to the Postal Museum today and had a ride on the mail train that used to take post across London using underground tunnels. The train is quite small and it was difficult to take photos from it so this is the train after hours heading into the tunnel. 
After this had my  first 'Escape room' experience. We did manage to escape, with just over a minute to spare , but needed a few clues to get there. Overall a very good day.
