Imagine a network of tunnels looping around Liverpool Street and Paddington covering six and half miles under London, just to carry letters.  No need to imagine because for seventy five years there was such a network.  Now it has just opened to the public at London’s at Postal Museum Mail Rail.

Postal Museum Mail Rail

Four million letters used to be carried down these tunnels every single day, 220 staff worked for twenty two hours a day shuttling the mail around the six sorting offices on the network.  The trains are tiny and not designed to carry people, all those letters and parcels hurtled along the dark tunnels without the benefit of a driver.  Now new tiny trains to carry people have been designed, you embark on a 20 minute ride pausing at a couple of those sorting offices to watch films about Mail Rail.

Once you’ve finished your train ride head up to ground level and explore the rest of the Postal Museum.  What started as a way of efficiently organising the troop movements of Henry VIII’s army became the very first social network.  Think of all those Jane Austen heroines writing letters and getting replies back on the same day, not as swift as What’s App but still pretty good.  There are all manner of post boxes, special bicycles and pistols to deter highwaymen on display.

In time the Royal Mail came to include the telephone system.  This telephone box with Button A and Button B took me straight back to primary school.  We were walked to the village phone box and it was explained to us how to make a call in an emergency.  You had to put your money in first, dial and if someone answered press button A.  At the end of call you pressed button B to get back any unspent money.  I never had to make an emergency call but children would often press button B on the off chance of retrieving forgotten money.

Here is something that even the youngest readers will recognise.  The plaster cast of the Queen’s head used on British stamps.  It is one of the most reproduced art works in the world and was made by Arnold Machin.  The first stamps to use it went on sale in 1967.  Who know’s as email, What’s App and the like gain in popularity maybe stamps will go the way of button A and button B telephone boxes.

    Ahhh I really want to do this! Need to actually get it sorted out, I’ve been saying this for AGES! #citytripping

      You do, it is brilliant

    I’ve just been reading a Famous Five book to my son which (as they all are) is filled with tunnels and passageways. He would LOVE this Museum, I can’t wait to take him! #citytripping

      I used to love the Famous Five

    What a fascinating place to visit. I need to go! I think my daughter and I would find it mind-boggling. I do hope letters don’t die out. You can’t beat receiving a handwritten card or letter in the post (although doesn’t happen very often these days)! Thanks for linking #citytripping

    I’m glad they’ve created a museum to honour the letter. It’s a bit of a dying breed! I need to go along to this place soon. #citytripping

      It will soon be half term!

  10. September 14, 2017 / 9:51 am

    This is absolutely on our list of things to do soon! It sounds so interesting and right up our street, especially me, as a history buff. We almost went just before the kids were back to school, but didn’t quite manage it – next holidays……

  11. September 16, 2017 / 7:25 am

    What a fantastic place. This is firmly on our places to visit this Autumn list.

    Looks like so much fun. I do love my instant email but there is something much more romantic about these little trains zipping around underground. Thanks for sharing on #FarawayFiles and PS – great to finally meet you in person last night

    I had no idea! I’ve never seen this before – so cool! Thanks for sharing with #FarawayFiles, Erin

  14. November 6, 2017 / 12:43 pm

    This is already on our list, thanks so much for sharing Catherine! Lovely post as usual! Question for you please – do you think our 18 months old would get to appreciate or probably best to visit just with the 4 years old? #MondayEscapes

  15. November 7, 2017 / 5:00 pm

    This is a museum I really want to visit. I think its something about the tunnels and all those letters! Amazing facts! #MondayEscapes

  16. November 7, 2017 / 10:35 pm

    I really want to visit this museum. Think my little one will love when she’s a bit bigger

  17. November 10, 2017 / 3:14 am

    This is so cool! I’m definitely sending my parents this post for their honeymoon in December. #MondayEscapes

  18. November 10, 2017 / 8:27 pm

    So charming. I would love to visit here! Oh, to return to London!
