Notice they play down the jobs losses. It’s just the ‘closure of hundreds of boxes’ - a total un emotive term.

LOOK British Railways then when it worked before £££££ Privatisation. How have we gone so sodding WRONG ?????

11:47 THAT GUY LOOKS LIKE HARRY HILL WITH HAIR, RESEARCHER TED EGGS FRIED? HARD BOILED? SOFT BOILED? POACHED?

Bloody hell that cable laying job looked cold!

This is one of my favorite old BR films.

20:42 goodbye old friend 😢

Track Ciruits are not something that terrorist should know about.

What's with the Hammer Horror movie music? I half expected Christopher Lee to start chomping on the technicians! I know progress happens, but I miss the old signalboxes and semaphore gantries. Some of the magic was lost when they were demolished.

Just pull those old semiphore signals down, don't save em. Mind you, I went to Collectors Corner (BR surplus) in the late seventies...but that's another story!!

As far as I know, I DON'T CARE

Love these vids. My wife is making High end Hifi systems, still with these same methods. Women arent just for washing, cooking, and making babies. Apparently lol. Dont tell her I said that 😂 Another great vid, please keep them coming. Thanks again. 😎👍

18:20 that looks nice and easy to understand 🥺

Back when we still made our own stuff, instead of ordering it from overseas.

On the cusp of digital, the manufacture of the components seems pretty labour intensive.

I had forgotten quite how awful 1970s background music could be. Thanks for the reminder!

High-tech back then, obsolete now. Much more interesting though.

So much of the electronics, racks and cabinets in this film I recognise from GPO (and then BT) SystemX telephone exchanges, which was also converted in the 1970s from analogue to digital - many of which are still in service today. Small world....

Listening to the soundtrack reminds me of Captain Scarlet! I was expecting the green Mysteron rings to appear at any moment!

Good heavens this is complicated stuff, All this is no doubt gone or replaced?

Since I commented on this post I went to work for Network Rail and I'm in a signal box with 4 NX panels like those in the film. By 2023 it will be closed and all the signalling controlled via computer screens from a location in Hampshire. Technology marches on.

This was filmed and produced in 1974. No wonder all the technology and details look just so damn dated. I hope they replaced all this stuff since 1974. 😫😫

Wow, this is the craziest wiring porn I have ever come across. Being a computer scientist since the nineties makes me feel lazy and stupid using IT nowadays.

Modern S&T equals the 'Dark Arts', god knows what it's like now (probably darker).

“Skilfully carried out by machines”. ??

Crikey! Paging Health & Safety inspector 20:43!

Sound effects library couldn't find Class 20 sound effects for 20:30 and settled for a tractor (not a Class 37) idling?

Whoever knew the manufacture of cables was so fascinating

Love it........ also feels like I am watching an episode of the sweeney.

Loved the Hymek music at 0:27!

Way over my head but still very interesting.

this is fabulous...how they mapped out and planned it is amazing...thanks for putting up!

How did they do all of this in the 1970s is beyond me and what an army of people that were involved in making all of this on time? Martin. (Thailand)

Amazing, beautiful electro mechanical workmanship, all custom built, which all probably ended up in a skip 10 years or less later. thanks for posting.....DA.

BICC Cables.. prescot and melling .

Absolutely amazing. I wonder how much of it is still in use. Someone may tell us.

. . . and all we have to do is buy a train ticket. Great video, very Britsh.

I was in the RAF at Lossiemouth at this time and used to travel from Inverness to Carlisle along this line at about the time this film was made and I never knew what went on. I only know there was usually a long delay at Carstairs, normally worse at night time.

The women soldering with theses fumes wouldn’t be a loud now

Love the old CAD, pencil and ruler.

Love videos like this showing how control and automation was done decades ago and how different it is today nowadays the whole system could be condensed into a few PLC's and one massive SCADA system how times change

At 26:00 the 50 is moving a full consist without the headlamp (switched on)! You wouldn't get away with that today! Had to edit my comment - it was so dark I couldn't make out the shape properly first time!

Train number display with catode tube. I suppose It was very expensive back then. I'm wondering if it was installed on each station or only for some central traffic management.

Is it just me, or has England got massively *worse* in every possible way compared to 1974?

I'm about half way thru this video,, I would just like to comment that back when this was all thought up, built and installed with attention to detail, strong hardy solid state electronic, boards, relays, et all,, I'm sure it had a long life window and cost a huge bundle. I keep asking myself if it's still being used or if smaller and smaller computers have been retrofitted to replace the old tech? I hope not, I understand new systems are faster and can be expanded upon with a minimum of trouble but this old stuff should hold up,,, I won't be holding my breath tho , ha ha.

The tune at the end is ace! Anybody know what it is?

wow god jobb done by men & wemen

The good ol days when stuff was repeated redesigned everytine it was installed allowing someone to come up with better ideas. Nowdays, Some programmer who has never seen a train comes in on a limited, and insufficient contract and makes changes that affect the whole network. In Sydney, AUS, some bright spark has programmed General otehr, or Trackwork announcements, to simultaneously talk over the station stopping pattern announcements, instead of wait until one has finished.. They haven't fixed it for years.

What a brilliant idea it was to outsource all the technological skills and manufacturing to Communist China. Make Britain Make Again!

Ah yes "Arklone P" 3:10 Happy memories.

The creation of this system is awsome but the destruction of the system which came before it was criminally wasteful. Some of it should have been left standing if only as a testiment to the fantastic engineers who spent there lives developing it.
