Last year our Curator Julian Stray gave a public talk on Mail Trains; this is now available to download as a podcast. The talk looks at the long and often strained association between the Post Office and the rail companies.
Interior of Travelling Post Office, by George Charlton, 1935 (POST 109/375)
Both underground and over, in sealed vans and Travelling Post Offices, mails have been conveyed, sorted and accelerated since 1830. Suffering the occasional mishap or celebrated by film makers (such as in the film Night Mail), the carriage of mail is considerably reduced today. Julian Stray’s talk touches on what went wrong, what changed, and why.
The talk is based on extensive primary research completed for the upcoming joint BPMA/Shire publication Mail Trains.

I love the idea that mail was being sorted on the move in a train carriage through the night. Such a far cry to todays system.
Love the poster a real piece of postal nostalgia.
I used to work on the GWTPO in th early 70s
