Empty Carriage

I always enjoy the rare experience of looking down empty carriages when travelling on the London Underground network. Here's a photo taken as I arrived at Barking Riverside on the Suffragette line on the London Overground.

the #SuffragetteLine is 13 miles and 58 #chains long.
Not a measurement I expected to see this century.
