Visit the Postal Museum to ride the Mail Rail

Going to the postbox used to be an everyday thing.  The Postal Museum and Mail Rail explores the history of the very first social network. Back when I was a BBC News producer, I was talking to the Post Office about a story and they asked if we wanted to film their underground train.  That was the first time that I had heard about Mail Rail.  Now everyone can visit and ride the Mail Rail at the Postal Museum.

Visiting the Postal Museum

Once upon a time if you wanted to send a letter you needed your own messenger.  The first ever social network came about with the creation of a national postal delivery network that anyone could use for a small fee.  The Postal Museum traces the origins of the system from an efficient way to organise Henry VIII army up today’s daily deliveries. 

My Postal Museum favourite things

Letter boxes in the UK are red everybody knows that.  Turns out that in the early days any old colour was OK until the distinctive red became the norm.  I rather like this fine green and gold Victorian pillar box.

In 1821 the first adhesive stamps were used on letters called the Penny Black.  In my stamp collecting days I was mad keen to see a Penny Black but never did, so was trilled to see a whole sheet of them at the Postal Museum (they don’t photograph well as they are behind an extremely thick sheet of protective glass).  Also on show is 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.

When I was a child red telephone boxes could be found everywhere.  How to use a telephone box in case of emergency was an important life skill.  My class at Primary School has a special trip to the Phone Box outside the Village Hall to learn how to use Button A and Button B.  Within a few years decimal currency and new machines made the lessons out of date.  Still it makes me feel very old to have a part of my childhood in a museum.

What is Mail Rail?

What is Mail Rail, I hear you cry.  Mail Rail is a six and a half mile long underground railway line that was dedicated to transporting letters and parcels across London.  Four million letters used to be carried on the trains 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 were tiny and not designed to carry people, all those letters and parcels hurtled along the dark tunnels on driverless trains. 

Mail Rail history

Back in 1911 London traffic was so bad that severe delays were being caused to the postal system.  Plans for an underground railway were drawn up.  In the 1920’s Mail Rail finally opened running from Whitechapel in the East to Paddington in the West.  Right in middle was the Mount Pleasant sorting office, one of the biggest mail sorting offices in the world.  Mount Pleasant is where you will find the Postal Museum and Mail Rail today.  Driverless trains ran underneath London delivering the post without delays until 2003 when Mail Rail shut.  The stations and tunnels lay quiet and unused until 2017 when part of the network was reopened as part of the Postal Museum.

Riding the Mail Rail

Two trains have been adapted to carry people.  They are very narrow and quite low (I’m six foot and sitting up straight was not possible).  No big bag or coats are allowed on the train, you can stow them in secure lockers on the platform before you board. Once you are seated a glass roof is securely fastened and you set off on your 20 minute journey.  Roy Middlesworth  , who used to work on the Mail Rail is your guide.  At you stop at old stations to watch a film projected onto the station walls.  Tickets for the Mail Rail are included in entry to the Postal Museum.  

Once your ride is over you can explore  interactive displays with some of the very early trains, the history of the route and even the staff lockers.  My favourite part was a sorting carriage which you can board and try to sort the letters as the carriage sways from side to side.

Tunnel Walks

If you are over 12 and have a fondness for high viz jackets and hard hats then a walking tour in the Mail Rail Tunnels is for you.  An expert guide will lead you down the tunnels and tell the stories of both the network and the people who worked on it.  Walks only take place on certain days, check out the Postal Museum website for dates.

  6. September 12, 2017 / 3:58 pm

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

    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.

  12. September 22, 2017 / 4:55 pm

    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

  13. September 27, 2017 / 9:34 pm

    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!
