pneumatic tube transports are still widely used within and between buildings. Maybe something similar could be retrofitted in here.

[@edhumphreys8990]

Most likely the sections that aren't being used as a tourist attraction, will end up with cabling. The first tunnel under the Thames, the Tower Subway, which was designed as an under-the-Thames foot tunnel, is now used as a super cable duct.

[@richkurtz6053]

Chicago has a similar freight unnel network under the city streets. It is connected to the basement of many of the buildings downtown and a rail network provided delivery service for packages as well as coal for heating to the buildings. The network was shutdown in 1959 and largely forgotten. In 1992, one of the tunnels under the Chicago river was punctured. This flooded the system as well as two dozen buildings that still had open tunnel connections. The tunnels are now used primarily for utility and communication lines.

Regarding vacuum tube mail delivery, Paris adopted such a system which ran from 1868 all the way to 1984 allowing the delivery of urgent messages within minutes. The network covered 427km at it's maximum, and carried up to 30 million message per year. Today the network is no longer in use but some of the pumping stations responsible for the running of the system still exist.

[@RobinHullBuilds]

I used to take Opinion Formers on Mail Rail in the 1990’s when I was a Public Affairs Executive at The Post Office Corporation. We had a few carriages with plexiglass domes and seats for the MPs, Peers etc to sit in whilst we ran them around the network. It was an incredible successful operation and transported vast amounts of mail daily. There was a proposal to extend the route to Willesden, the home of the Princess Royal Distribution Centre. The PRDC was the southern hub of the Travelling Post Office and the Networker system. We actually opened several dedicated Sorting Offices on the National Rail Network. My last opening event took place in Bristol. When Mail volumes dropped and the reliability of EWS to deliver Mail by train became a massive problem, we looked at moving Mail to roads. A study was undertaken to open Mail Rail to Oxford Street shops, and by doing so it would reduce the amount of vehicular traffic. But, the study showed that the idea wasn’t feasible and Mail Rail closed. The Travelling Post Office network also went the same way. The PRDC is now, from what I understand, mostly used as a vehicle hub?

[@cardiffian558]

PRDC was built on railway land with the hope that most of the mail would be transported by train. Several passenger trains were converted to carry containers for exclusive use by Royal Mail, even being painted Post office red in colour. A reversing spur was built for the trains at Kensal Rise on the high-level North London line at a considerable cost. However, train use reduced dramatically within a few years of its opening: now 50-foot long articulated lorries arrive every two minutes at the centre from all parts of the country. The 'mail rail' from Paddington was going to follow the route of the Bakerloo line which runs alongside the PRDC at Stonebridge Park. There are still a dozen derelict mail train carriages on a spur outside the centre after twenty years not moving!

[@peterknight6535]

I remember that proposal, but R.M had decided that along with the T.P.O. network it had to go.

[@cardiffian558]

Further to my previous message, Royal Mail has just announced that they will be ceasing using trains from next October. They have also ended the contract with DB Rail as from that date. The diesel lorries will be converted to electric vehicles over the next three years (yeah, of course!). {See the current "Rail" magazine for full details of this change.} This brings into question the compliance with planning permission for the £5 million depot.

[@RobinHullBuilds]

@@cardiffian558 oh that’s interesting! One of my other jobs was to organise the “official opening” of the new hubs being built to accommodate the new networker style trains. Mostly they were just a big shed alongside the track where the train could be off-loaded of its York Roll containers. My last event was at Bristol Parkway. We chartered a train and engine which took guests to the new depot. They were met on arrival by a jazz band and catering. Then the local mayor (I think) officially opened the “station”.

Letter posted in Bristol would be sorted in Bristol, and if going to Manchester would be put on a train going to Manchester (not necessarily a Travelling Post Office train). On arrival in Manchester, it would then be sorted for the specific delivery round.

Great video, and you should definitely do one on the Thames Tideway Tunnel, if you haven't done already, since that's going to have a massive effect on our lives with the majority of people not even knowing it exists!

[@christopherhall6494]

I remember being part of a group looking into the possibility of using the Mail Rail trains to deliver stock to the large retail outlets in Oxford Street, e.g. Selfridges. The trains passed just below the basements of these premises, so it was technically feasible.

[@tomthornton6259]

I feel like that should be done still, or maybe the whole system could reconverted for parcel delivery? While barely any letters are sent anymore, parcel delivery and logistics sectors are bigger than ever! I feel like a huge amount of vehicles could be taken off the road and replaced with systems like this, with people on bikes and small autonomous vehicles being used to deliver said items from the nearest station to their final destination. I feel like it could still have a future and help efficiency and reduce pollution and congestion.

[@Mancozeb100]

Good to hear about this. Very interesting. One item - @3:50 … your reference to “an electronic railway..” it really would have been an “electric railway” - control systems would have been quite basic back then - consisting of mechanical switches, usually with human operators. Electronic ( even primitive electronics) controls didn’t really come into use until much later in the 20th century. So, even today - “electric” trains may be controlled electronically - but the train itself is electric.

Mail Rail can be seen in action, in the Bruce Willis movie "Hudson hawk", where it is portrayed as "The Vatican's mail system". The extra's in the scene, are (or were) Mail Rail employees. Watch the film and you will see it in action.

I remember reading about the Post Office railway in the London Transport Magazine back sometime in the early fifties. My Father was a London Transport employee (worked at the Acton works), so he got the magazine regularly. The PO railway was featured as something which would be of interest to the the staff of London Transport, especially the railwaymen.

[@producedbypodcast]

[@simoncroft9792]

Backin the 1920’s mail delivery was next day or even same day! Grandad in business said there were several post deliveries to his work every working day!

[@wideyxyz2271]

Very true, up until about ten years ago we used to get morning post then late post in the afternoon. Now we only get something around mid-morning!

[@kiwitrainguy]

When I sorted mail (NZPO) in 1977-78 the saying was "Sorted today, delivered tomorrow". We now have mail deliveries three times per week. In my area it's Tuesdays, Thursdays and Saturdays.

[@paulhaynes8045]

When I was a kid (50s/60s), mail arrived the next day, wherever you sent it (and all at one price!). If something didn't arrive before breakfast, it might come second delivery (around mid-morning), and if it still hadn't turned up, it would usually make it in the afternoon post. In some places there was an evening post as well (just like there were evening newspapers!). Then the two-tier system was introduced - first and second class - mail would still get there the next day, usually, but only first class was guaranteed to get there on time. Then Sunday deliveries went and collections times were reduced (our nearest mail box, now has only one collection a day - at 7am! - and only on weekdays. We now get one delivery a day, usually about 10am, and only on weekdays. And even first class letters don't always get there the next (you have to pay extra for guaranteed next day delivery). Although, admittedly, I hardly ever send anything my post these days (even renewing passports - the example used in the video - can now be done online), and most of the post we get is junk mail, which goes straight in the recycling. I think we get more online deliveries via the Royal Mail than we do actual letters. The final nail in the coffin (from my personal perspective, at least) was the introduction of different charges for different size and weights of letters. We now have a situation where we have very little idea of how much a letter or package is going to cost (and, even if we do, it's unlikely we have the right stamps to hand), so for almost anything I want to post, I now have to walk half a mile to the nearest post office, and queue up for at least 20 minutes. If you don't have a local post office, as many don't these days, you're buggered.

[@edhumphreys8990]

MailRail ended when the decision was taken to build a massive sorting centre in the outskirts of London. The location chosen has good links to the motorway network and is next to one of the main railway lines out of London. The gigantic sorting centre is located in Stonebridge Park NW10. There was no need to shift mail between the various London sorting depots and a railway station, as it could all be done in one gigantic centre, with modern automatic sorting machinary. The centre at Stonebridge Park is called The Princess Royal Distribution Centre.

[@P6UL_K]

Interesting, I used to ask about the history of that building when I visited on numerous occasions whilst delivering mail there. There were never any machines in the main expanse anymore… It just turned into some sort of cross dock facility for mail arriving from different places to be reshuffled about in the yorks and then back out on lorrie‘s again

[@paulhenry7]

Automatic sorting machinery requires the use of optical character recognition (OCR).

[@mlchallenges9043]

[@robertsmith4830]

Actually, mail would be delivered the very next day, not in a couple of days. And mail posted within a town or city would often be delivered the same day!

The other thing to note is that hardly any mail is sent by rail anymore.i believe the terminal in West London is Willesden. This survived very short time e. For its intended use. I believe it’s still used but nothing like the volumes it was built for. I took a trip on it last Christmas, I’d recommend anyone to do the same.

[@Ron-u1z]

Stop bullshitting. I worked for royal mail and it was shut as the 8 London mail centres were shut down to 2. It was due to falling letter numbers. That's why they have just stopped sending mail by air this year. Also the reason they got rid off the travelling post office ( TPO) on the railway. That's why the service is terrible now. Letters being left in the slots for days at a time because the posties walks are far too big. It's all about money now and not service. When I worked as a postie not one letter could be left undelivered, or you would be done for wilfully delay and sacked. All this mail not being delivered for days at a ti.E are with the managers blessing. It's all about parcels now. And then the CEO of RM got caught bullshiting parliament. He was a little sniffling knob anyway.

Fascinating to see what this Mail railway was built for delivering mail underneath Central London. Long before Crossrail came which is now the Elizabeth Line.

[@P6UL_K]

Great video! I know you mentioned the (then) new Royal Mail terminus that was built out in West London at Princess Royal… The irony of that now is that Royal Mail have also decided to stop all trains running out of there delivering mail across the country and reverting to an all lorry service only! It’s crazy given the pressures on trying to be environmentally friendly and a big privately run company like that is clearly putting profits over doing what’s right. If memory serves there were eight platforms I think at PRDC, which gradually got reduced down to only two or three I think when I was there last a few months ago. Rumour is that PRDC is on leased ground and the government wants it to turn it into some sort of maintenance terminal for the HS2 railway line

[@petecollins4925]

Don't know how but this video just appeared in my recommends. This really takes me back to my days in the 1960's when I joined the GPO as an apprentice electrical technician. Although I worked for the overground section looking after the maintenance side of the post offices and sorting offices there were lads allocated to the railway who attended tech college and training courses with us. I only got to visit the railway once as one of the stops was beneath King Edward Building which at the time was GPO headquarters and was one of the sites I worked at regularly. Known to all and sundry in the GPO as KEB it was an enormous building with nearly as many basement levels as there were floors above ground. There were rumours of other closed off underground tunnels which had been used during WW2 but we never did stumble across anything like that! Also interesting about the mechanisation which came about with the introduction of postcodes. Our apprentice intake year were the first to be trained on the installation and repair of the new sorting machines. Proving trials and training for the post workers who were to operate the encoding desks was done at an old GPO district sorting office just off Oxford Street, many happy memories of my final months of apprenticeship being there.

Could you also convert all of the 1973 stock trains into an air-conditioned maximum speed 78 km/hours (48 MPH) re-refurbished and make it into a 8 cars per unit if that will be alright, and also extend all of the Piccadilly train stations to make more space for all of the extended 8 car per unit 1973 stock air condition trains and can you also build another Mayflower and Tornado Steam Locomotive Companies and can they order Every 87 Octagon and Every 48 Hexagon shape LNER diagram unique small no.13 and unique small no.11 Boilers from those Countries such as Greece, Italy, Poland, and Sweden, can they make Mayflower and Tornado Steam Locomotive speeds by up to 147MPH so you can try and test it on the Original Mainline so it will be much more safer for the Passengers to enjoy the 147MPH speed Limit only for HS2 and Channel Tunnel mainline services, if they needed 16 Carriages Per units, can they use those class 55’s, class 44’s, class 40’s and class 43HST Diesel Locomotive’s right at the Back of those 18 Carriages Per Units so they can take over at the Back to let those Mayflower and Tornado Steam Locomotive’s have a rest for those interesting Journeys Please!!!!, oh can you make all of those 18 Tonne Boxes of Coal for all of those 147MPH Mayflower and Tornado Steam Locomotive’s so the Companies will Understand us PASSENGER’S!!!! So please make sure that the Builders can do as they are told!!!!!!!!!!!! And PLEASE do something about these very very important Professional ideas Please? Prime Minister of England, Prime Minister of Australia, Prime Minister of Sweden, Prime Minister of Germany, Prime Minister of Italy, Prime Minister of Poland and that Includes the Mayor of London.

For goodness sake! Put some punctuation in. Break up the text with some paragraphs! Then more people might bother to read your (actually quite interesting and certainly detailed) stream of consciousness. Which, I presume, is what all we commenters ultimately want.

[@dpsdps01]

I cannot help but think that it must be cheaper to expand the diameter of these existing tunnels than build completely new ones outright - perhaps they could be redone to double as a new underground line. Large profile like the Elizabeth line would probably not be feasible, but small profile such as the piccadilly line should be doable. Wonder why TFL didn't at least study that proposal.

[@steffenfrost995]

However in the deeper analysis the route is broadly served now by the Elizabeth Line itself and expanding tunnels is more complicated than running a TBM through virgin ground.

That's a very weird graph at 2:39. The axis goes from 50 to 100 to 500?

[@theosergiou7406]

You privatise the major stations first: Paddington and Liverpool streets, then you make the sustainable project obsolete.

[@chloelau8291]

You can still ride it now! Comes with a Mail Museum ticket!

[@michaelbannister7086]

It would be nice to explain how the trains work. If anyone would like to see a train away from the tunnels, the Buckinghamshire Railway Centre at Quainton has one in its museum.

[@Dovietail]

Y'all used to have like 5 or 6 postal deliveries a day in Victorian London, didn't you? Unreal!

[@isabellemartin4728]

Wow, very interesting !!!

“I emailed a railway museum to ask for a tour and was surprised when they agreed”

[@nielsdanielbuch9022]

Im thinking a look into the London sewer network could be interesting, starting with The Great Stink.

[@julierobinson3633]

You just KNOW that some of those workers got a quick lift sometimes on those trains...

[@madmachanicest9955]

It's not a city thing but the US state of Florida was millions of miles of natural underground tunnels full of fresh water that zing and zang all over the place . Many are so big people can sub throw them.

[@harrishartman]

as south east asian, specifically in bandung, hopefully our public transportation getting better.

[@Unknown_Ooh]

Has absolutely nothing to do with this video

[@justmeajah]

Wow!! Amazing video!! Wow!! I know this from The Amazing Race!!

[@rrotwang]

NYC had an air tube system Some still survives

[@SimonBanfield]

BT Tunnels under London next please...

[@little_britain]

As always, one why leads to another. Why did the government require the postal service to stop using London's mainline stations? I will now have to research into that.
