New London Underground trains: Your thoughts

[Dstock7080]

Nothing wrong with C Stock, but the ventilation (and being out in the sun a lot of the time) made me hate them with a passion on hot days.

To go from mobile greenhouses to air conditioned trains will be quite a shock to some people!

When car 6513 had the trial air-con equipment it was very good, making use of the full ducting installed to all C Stock that were refurbished.

Why don't people like the C stock?

I don't see anything wrong with it, It does the job and the only thing I can think of what's wrong is the tattyness of them thanks to wear+tear as well as the graffiti they seem to pick up!

The lack of ventilation is a huge factor, as is the jerky acceleration/braking they seem to exhibit. Compared to them the new S Stock is a luxury limo!

The PA speaker volume linked to ambient noise didn't/doesn't seem to work too well. Rather than gradually turn up or down the volume (a very good idea, incidentally) it seems like there's only two volume levels. Normal or eardrum busting - and it can switch part way through an announcement too!

I experience both ends of the spectrum really on my daily commute from Brixton to Regents Park, and have to say that whilst I love zipping up and down the Victoria line I do have a soft spot for the quirky 72 stock. Might think less of it if I had to go more than one stop though!

The C Stock is very jerky, the D stock, even before its refurbishment, feels much smoother and quieter.

I like some of the new stock, especially since the 67,72, 73 etc are very similar, it adds more variety, and an improvement in service is always welcomed. however I don't like the look of the 09 stock, if it wasn't for the colours and logos it wouldn't look like a LU train! I hope any new stock keeps with the same shape/design that all the other deep level tubes have had for about 100 years (and all the current stock except the 09 has)

Well, you can keep the nice old stock for a while yet since the 1972TS MkII will be with us for a fair amount of time.

Still, the C69/C77 Stock and D78 stock are miles appart technology wise, the 'jerkeyness' on the C Stock could be to do with the older braking systems, or possibly bored drivers making use of the very old braking systems..?

I presume the jerky ride on the C stock is down to having 3x 2 car units to make a up a 6 car C stock. Especially departing Baker Street eastbound when the front motor car is off the juice rails going over the points, the rear and middle ones are still powering and so on as they all cross the gaps causing a jerky ride.

You will get that on all the RPA controlled stock (1967TS, 1972TS, 1973TS, C69, C77 and D78) but to a much lesser degree on the D78 due to an improved control system.

Most units are made up of two motor cars and some trailers, a full train will usually have four motor cars that will cause the jolting on the couplers you mentioned.

The issue on the C stock that makes it seem worse is not only the build quality but as you mentioned, the stock formation, on other stock there is one wedgelock between the two units forming the train, with more rigid semi perminant couplers elsewhere.

You can make it a less jerkey ride by some careful drivng, but since the RPAs on pre D78 stock are not linked in any way other than the CBTC commands, it can be very hard when it picks up if you're already in Paralell.

I thought that the wheelspin relays and door interlocks were the key culprits for motors dropping out when pulling away on C and 72 stock. Though difficult to say exactly when you only feel the consequence and are unable to actually see the causes. That is what the car examiner would tell you though - if you could drag them away from their kalooki school long enough.

I'm not a Bombardier fan, but the new stock on the Metropolitan line really is top notch. Particularly like the fact it automatically ups the volumes on announcements depending on the noise levels on the train.

 

[jon0844]

The C Stock does this too, but seems to only have two levels; quiet and super loud - and there's no smooth adjustment of the volume either.

A stock were great - the last real connection with the Met Railway's history of mainline aspiration.

I don't miss the 67 tube stock so much... but it's strange to think that when I first travelled on the underground they felt like the new and modern trains compared to the 38/56/59 stock on the Northern/Bakerloo lines.

Welcome to the forum!

I miss the 1967 stock more than the A stock because I never travelled on the latter. I do, however, remember travelling on the 1967 stock a few times. The last time I went on one I was near the end of the carriage by the window. The breeze when the train was travelling at speed was welcomed given the fact that it was a warm day in June, and the noise and motion of the train made for a fun experience.

It's strange to think that next time I go on the line, the trains will be very different.
