To answer the question originally posed by spsmiler, there isn't a lot of verifiable information available online, but consensus seems to be around 12 feet or a rather alarming 3.7 meters. That is alarming. Even a gas meter is only about 30cm (a foot) in it's largest dimension. 12 gas meters wide - a non-standard unit of length if I ever heard one!

I seem to recall reading that Archway was the last deep-level station to retain tungsten lighting, surviving until 1980. Were there any other stations that retained it until relatively late, or was Archway an anomaly?
Apart from the (new in 1967) northbound platform at Highbury, the Northern City Line remained completely tungsten lit until it closed, pending transfer to BR, in October 1975.

Has anyone seen the new platform indicators at Stratford? I saw them on the eastbound platform yesterday. What do they look like?

On a separate note, could members actually read other people’s posts before commenting, and accept that there are more considerations with automatic announcements, other than the fact that you may find them annoying. We have a wealth of knowledge from people “on the job” or “in the know”, and we should be more careful than to just ignore their input. 👍

I do wonder, is all this automation really necessary to achieve an additional 2 or 3 trains per hour? The District Railway was achieving 43 TPH and more in the days of steam working and manual semaphore signalling. If this 43tph District Railway service was like maybe 75-100 years ago I suppose we cannot compare it to modern days because we have to consider back then how slow the trains move too. The S stock has a max speed of 62mph (I know A stock is 75mph but this is District Railway). With greater acceleration capabilities, we need great frequencies, yet also not too slow journey times. There is a bit of illusion that 43tph is able to move people faster, but if the section of line is saturated it is definitely not going to move quickly. I suppose this is a give and take situation. It also depends on the safety distance set in CBTC so getting 33tph is already pretty great considering you averagely wait 1 min less for Hammersmith & City or Circle line trains, and perhaps 2 mins less for Metropolitan and District line trains. Pretty crucial especially when you want to change trains. I also wonder how often such high frequencies were achieved in practice? There is also the factor that there were far fewer passengers in those days, so the service would have been less susceptible to delays caused by overcrowding. Furthermore, I doubt that the efficacy of the signalling system which permitted such high frequencies back then would pass today's standards!

This has brought back some very happy memories of a very cold January in 1980. I was the fireman of Coventry No. 1 used in the video and had the 'unfortunate' task of keeping Annie warm on the footplate between takes. Well someone had to! That's what I love about this forum - posting a random pop video containing an ex-Metropolitan line station, and somebody replies who was involved in the video! Great stuff!

Not wide enough would be my answer! I remember the old Angel platform, and how crowded it used to get in the days when the Northern line service was, shall we say, not up to standard.

When Essex Road closed in October 1975 pending transfer to BR, were the lifts original installations from when the station opened?

I seem to recall this too - maybe for engineers' train or special workings. In the end, the engineers' trains were fitted with ATP, so the colour light signals are somewhat pointless. I definitely recall this as well. They were certainly used in this way for the Central Centenarian tour in 2000. I forget what the actual arrangements were for that, however it was certainly running under signals. There must have been some serious work gone into the planning for that one. I have no recollection of that tour - do you remember the itinerary?

Being a ex employee of Morden 1968-1976 Im writing a book for a friend and would like to know please when was the first 1938 stock entered service at Morden, and when was the last and very much a lot more. Im now 74 and my brain is fading fast. I remember fondly my motorman Charlie Grant many a driving trips with him, then driver Philip Rattle, and chaps I knew then names I don't. So would anyone with their underground stories like to appear in ClickityClack if admin doesn't mind my email is david464u@icloud.com and my website www.jdbbooklets.org.uk as I fund raise for MNDA. I loved the tube I dont know why I left. We used to live in Sutton now we live in Norfolk but mysoftness is still the underground. The new trains now are armchair drivers and dont know what a temperamental deadman feels like or the brake handle. I loved the feel of getting the ding then you wound her up and the trundle over the points in platform 5 and the tunnel downhill to South Wimbledon and the old 38s moved. <<superteacher>>: Post moved here to create new thread.From the excellent book on the 1938 Tube Stock by Piers Connor, the first 1938 train entered service in June 1938. I can't recall if it mentioned that depot it came from, although I suspect it was Golders Green.

Surely the signal aspects appear in the cab, so the traditional line-side signals are only used if the cab system fails? I don't think LU has ever had a system where signal aspects appear in the cab. On the Central Line target speed is displayed in the cab and the fixed signals are sort of supplementary. They have definite value and degraded working is one but not the only. However the automatic colour lights that are provided between stations on plain line sections on the Central have always interested me somewhat. I love fixed signals and hate and loathe their removal so I'm not complaining but I've never been quite sure on the stated purpose of their retention after ATP was rolled out. I have read things that suggested there were originally some ideas which were later dropped about perhaps allowing trains without ATP to run on the line as well and the fixed signals were intended for them (I'm talking about the automatic signals between stations specifically) but I dunno really, I suspect they were probably retained for degraded working. The original Victoria Line system had a way of displaying the current code in the cab but the problem was that was all it could display. What it couldn't tell you was that the code was gonna come down before it did. I believe that's why the 67s were limited to 25 mph in Coded. Because the problem was if not you'd be going along at full speed with your 420 code completely fine, then suddenly the train would receive a 180 code and it'd trip. And there was nothing you could do about that so 25 it was.

The TfL board was told last week that plans are being made to re-open the Waterloo and City line in May or June. Interesting. Presumably details weren't given in the public part of the meeting about how LU propose to resolve the lack of social distancing possibilities in the crew room at Waterloo, given that seems to have been a significant part of the problem? Hopefully the social distancing rules will be dropped by the summer.

As it's been a while since the above was posted, a quick reminder is in order as there have been numerous applications approved recently, with very few introductions.
I don't need to repeat what is said in whistlekiller2000 's post above, but please, if you are new, don't be a stranger and introduce yourself!

There were 20-25 gaps in the Central line service early on Saturday evening, even in the central section of the line. That is a decimated service. 20 trains cancelled, which wasn’t the worst as the Jubilee had 22 and almost half service, although a full Line - regular service afforded a “good service” message. 😁 I heard that back in the 70's on some Saturday evenings, the Met had only four trains running! Hence sending the odd C Stock up to Amersham to cover!

It seems that absences from work due to Covid are very high for train operators. Are buses, for example, experiencing the same level of absence?

It’s been the off peak situation for quite a few years now though. If they plan to run semi-fast services in the west, I don’t see why they can’t do it in the east. It would also be nice to get the peak service level back to what it was 30 years ago! Whenever I have compared services today to those of 30 years ago I've been told that the service is as intense as it could be. No-one seem to believe otherwise. I know that train frequency is less than it used to be because I lived it 30 years ago - and still have a 1982 timetable book. I do not have the data in front of me at the moment but it is something like 6 trains per hour in the rush hours (including some trains which terminated in the bay platform at Ilford) fewer today than there used to be. Is it any wonder that before the pandemic services became so overcrowded that passengers would be left behind? I was always told that it was because passenger numbers had risen - this may be true but its not the true reason. I feel sure that especially passengers who travel to Stratford or Liverpool St to / from stations Romford and onwards will feel very put out / short changed at the loss of faster services - six extra stations* (Maryland, Forest Gate, Manor Park, Seven Kings, Goodmayes and Chadwell Heath) and noticeably longer journey times. *(Even more when services start travelling underground - Whitechapel) It would have been far better had local services (so called 'Shenfield Metro') not been hived off from East Anglia services and instead just as the west will include trains to Reading off-peak services to the east of London included trains to Southend On Sea^ and some Great Eastern Main Line destinations. (^ie: retaining the off-peak Stratford, Ilford, Romford and then all stations service) Agreed - if traffic levels return to pre-pandemic levels, the 9 car trains will not offset the reduced services. They should have been aiming for 15tph from the core to Gidea Park /,Shenfield, with a few extras from Chadwell Heath to Liverpool Street mainline.

From May there will be a mix of 315s, 7 car 345s and 9 car 345s. On the East they are moving to all stops all day, with almost 100% of services running to Shenfield on Monday to Fridays. There will be a slight reduction in peak services, but capacity will be maintained eventually when everything goes over to 9 car operation. They will probably get away with reducing services due to suppressed demand due to the pandemic. But I’ve never understood the obsession with removing the semi-fasts in the peak, especially when they are being retained in the west. All I can say is it won’t be popular, but then again operational convenience seems to trump it. Are they still planning on running peak trains into Liverpool Street main line when the core opens?

boo if all trains will soon be all stations - sad news. Its bad enough that this is already the off-peak situation. re: the impending longer trains, I must dust down my camcorder for present-day length trains. I'll be shopping in Ilford later this week... It’s been the off peak situation for quite a few years now though. If they plan to run semi-fast services in the west, I don’t see why they can’t do it in the east. It would also be nice to get the peak service level back to what it was 30 years ago!

Believe they're going at the May timetable change. Is that when the semi-fasts are going too, or has there been a rethink on retaining them after the core opens?

I presume this is for the platform extension work? Luckily I just so happen to have already booked A/L for that week . This follows the Easter Weekend when there are no trains for 4 days between Liverpool Street and Shenfield. Nine car trains will be able to run in and out of Liverpool Street after this. And I’m assuming that this will spell the end of the class 315’s shortly afterwards?
