Thanks to Geoff I appear to be becoming a train nerd. But as an electronic engineer I love the shunt/series/parallel labels as they make perfect sense and describe exactly what they do.
Very true George, I am somewhat annoyed that the explanation of these terms in the video was not better, for instance what happens to the electricity not used for traction - heat. I guess the S stock has thyristor control or something.
@@ianmurray250 I've watched it and can see where there's loads of extra bits to add, but I think the way it was described was an easy way for a wide audience to get the idea.
Actually it's bollocks. Shunt has resistors, series is a series circuit and parallel is a parallel circuit so parallel is four times more power than series and shunt chucks out a lot of the power as heat. If you ever saw a train with the grids glowing you'd know what I'm on about. Never drive a train in shunt/inch for more than a minute and usually round the yard, which is what it's there for.

10:00 after, I can sense the sorrow within Alex, I can tell that he would love to spend just a moment longer with the train the started his career as a train driver. I've recently experienced the same feelings as my primary school moved into a new campus. A perfect display of the love and compassion from a driver who loves his hip and train. Like Alex, a kiss goodbye to the c stock, although I never got a chance to ride on one, may your legacy lives on. P.S. in HK, where I live, we're facing the same situation and feelings soon as the old trains on our railway (the m-train and the MLR, both built by Metro Cammell) is going to be retired and presumably scrapped.
Fun fact : the MLR mentioned above is based on the mark-3 based 2nd gen EMUs on the British mainline, namely the 317. The m-train on the other hand is said to be based on the 67stock, although I saw more resemblance betweenthe m-train and the subsurface stocks, namely the C and D stock
@@volker8760 You say that the MLR is based on the Class 317 but that train was manufactured by BREL (British Rail Engineering Ltd), not Metro-Cammell. Was there cooperation between the two companies?
For anyone wondering, "series" is switched so several motors are lined up one after the other in the circuit - the current has to go through all of them, thus increasing resistance. When the controller is switched to "parallel," the current goes through each motor independently, thus there is less resistance. It's a very simple way of controlling acceleration, but it works.
And, on top of that, if I recall correctly, both series and parallel each have several stages of resistance that a relay or set of relays or contactors switch through automatically, based on the current being drawn by the motors. This ensures that (a) the motors don't overheat and, and (b) the train doesn't shake violently whenever starting to accelerate.
Outfrost I think you are referring to the RPA (rapid pneumatic accelerator), which could be heard in operation as the train accelerated from rest as a rhythmic clicking.
@@RJE48 Yes, although the 1960TS is a much rarer sight, only two 1960TS trains are left. There's quite a few 1938TS carriages scattered around the UK. Plus this is officially the oldest running train on the Underground, as the A Stock is gone.
So that's what it is! I think I saw one once, years ago, and couldn't work out what it was - it was obviously an engineering train of some sort but beyond that I couldn't find any details. My description of it as "like an old train but armoured-looking" didn't help either, lol.
@@Dogtor_Orsum It's been quite a while since one of them saw service (withdrawn in 1994), and it has been changed quite a lot since it left service. There is one in original condition with the heritage livery in preservation. It is essentially two 1960 Stock DM's with a modified 1973 Stock Trailer. When in service, the units had 1938 Stock trailers instead. It will probably be going in the next few years, with the 1973 Stock becoming available upon withdrawal, it will probably be heading to the scrapyard.
The C Stock which originally served the Circle, Hammersmith & City and the Wimbledon to Edgware Road branch of the District line, passed over those duties to the S Stock. RIP C69/C77 stock. Thank you for many years of faithful service.
Intriguing to see at 1:35 what looks like a Cravens 1960 stock unit in the car shed alongside the S stock. A graphic demonstration of the size difference between tube and cut-and-cover rolling stock! (Edit: comments below confirm that it is the Track Recording Train formed of 1960 stock)
I hope you're still around on UA-cam when they replace the old '72, '73 and '92 stock with the (still to be properly named) "new tube" in a few years time. Mainly because the other few videos on the transition from old to new stock have been fascinating. The only difference is we'll all be a lot older and greyer by then!
The front, the flashing lights, the closing door sound and the announcements make me feel like the C-stock is just a larger version of the 1972 stock used on the Bakerloo line.
I got an opportunity to ride a C stock train only once in my life, and I was too young a kid to remember anything. All I recall is it was a journey from King's Cross St. Pancras to Tower Hill, and it must've been on a C stock on the Circle. I only got to know them a bit through World of Subways later on.
Great video. I drove c stock from when they arrived. Rickmansworth crews hated them. They were happy when they were confined to met main only. For myself I loved them and drove them till I retired In July 2000.happy days.
7:36 this move still happens every week, only they join the Underground at West Ruislip now. You can usually see a train in the LUL sidings at West Ruislip.
I liked the C Stock for two reasons: The distinctive motor noise was very similar to Warp Drive on the original Star Trek. ua-cam.com/video/_DN3KW3k0Ao/v-deo.html I always thought that the sound effects on the Bridge should have included a grasshopper-like compressor kicking in and out. Also, before the late 70's the suspension was all over the place giving the trains a really wide rocking motion and you could pretend to be surfing by not holding on (later rectified with dampers on the bogies).
Like most new tube stock, C-stock were a great improvement on the previous rolling stock in 1970, but old age, lower maintenance prior to replacement and passenger expectations all take their toll on passenger experience. The main difference is that C-stock are 1969 design mechanical and can be understood by drivers when they go wrong, S-stock is 2008 design with computerisation making it much harder for a driver to repair on the fly if required. On the other hand S stock can report potential problems before they happen. In theory although there is more to go wrong, less should. It'll be interesting to see what passengers think about S stock in 2048 when they are replaced with .... well goodness knows what London will need by then.
The C Stock was genuinely the OG Tube Train they were amazing, they had nice LT117 DC Motors which sounded amazing and they had a really nice look and feel to them
Good video, and what have I missed? Only starting going to London 3 years ago. Managed to get a D-stock single and only chance ride! No c-Stock :( Great Video.... LOL my trips are off Pendy at Euston across the concourse... And then I'm a mole all day!
He probably didn't have enough footage at that particular station so he used footage recorded at a different stop earlier that day on the other side but then flipped it.
I remember checking the installation of the Connect train radios and ancillary equipment on the C stock in Hammersmith Depot in about 2005/6. BTW doesn't Hammersmith Depot have the longest non thru carriage shed in the country? I seem to recollect that you could park up 3 C Stock trains in a row on the same road inside the shed.
@@geofftech2 To be honest, I’ve never seen this before. Literally, one of my all time favorite UA-camrs has made a reply. I’ve been following you through all your videos since 2013 since I absolutely love trains.
The Bakerloo line must be the only line that has old stock in use still?? I hope they keep them running. I love going on that line and those old stock trains!!
Compared to a traditional 9 notch controller and air brake, these look rather simple to operate. I like that the motor and brake controls are cleverly integrated.
Done a few Edgware rd - Wimbledon’s on these... not to mention a few Sunday circle duties. What are they doing with the triangle now? Does anything get stabled there? Nice to see the guards panel was still there.
The C stock was in the worst condition than the other Sub surface stock but that's only because they didn't seem to maintain them that well. They still bring back a lot of memories however since I used to travel on them a lot
Are there any films of the old slam-door Metropolitan trains? I remember riding on those out of Baker St to Preston Rd in 1957 and again between Preston Rd and Wembley Pk en route to Stanmore.
That was fascinating! And now I know what's going on when drivers move that lever around. (See it a lot on tram videos, too - of older model trams). The train must be electrified by a third rail because there are no overheads. I wonder why different places electrify their trains differently?
The Underground uses fourth rail system as that's what was originally developed. Most of the old British Rail southern region use third rail as that was the standard in the late 19th/early 20th century, as well as many lines that run in narrow tunnels where there isn't room for overhead wires. Most services north of the Thames use overhead electrification due to it being more reliable and powerful (fastest third rail train can go 108mph versus 357.2mph for overhead) and they were mostly electrified in the last 50-60 years
