I know that the WTT details the running of trains under their train or set numbers. What is the correct term for the document which tells train crew what their duty is, which train to pick and where, etc? I remember on the Central in the seventies they were linen back documents which folded up. Any examples anyone can post of either then or current practice? Many thanks
Thread title capitalised. Thanks DomK

If they're what I think you are describing they are WW2 "dragon's teeth" to prevent attack by tanks etc of the aerodrome at Fairlop....

they were not called headlights, but marker lights and were not designed to light the route ahead, they were to mark the front of the train. On the 56/59/62TS, the prototypes had lights to code the destination, these were dropped on the production models which featured just two lights side by side on the opposite side to the driver (in case one bulb blew the train could remain in service until a car examiner fixed the problem). The bulbs were only 50W each. No need for illumination of the tunnel, and better visibility of signals in the dark.

the requirement to slow to 5mph up to the station starter is because of "compromised" overlap distances on said starter. As all trains would normally stop, there is little need to have an overlap on the starter which accommodates full line speed. This enables the signalling to be squeezed up, allowing trains to be closer together at stations, thus allowing one train to run in as the proceeding one runs out. There would potentially be a risk if a train were to pass through a station at higher speed and another train had stopped just out of the station.

I think the biggest problem was in 1993, with the following summary taken from Underground News
[Thu] 25.11.93 - The biggest power failure and evacuation in LT's | history occurred yesterday. More than 20,000 commuters had to be | rescued from stranded trains trapped in tunnels when power failed | at 07.10 on the eastern sections of the Central, Circle, District, | Hammersmith & City, Metropolitan and East London Lines; the back-up | supply failed 20 minutes later. Services were restored to all lines | except part of the Central, by mid-afternoon, when LT engineers | traced the failure to a cable fault near Newbury Park station. | However, as the evening peak was building up, power failed again | stranding six trains between Leytonstone and Stratford. As a result | LUL has cancelled services east of Liverpool Street today.
| [Fri] 26.11.93 - The Central Line east of Liverpool Street will | again be shut this morning because of random electrical short- | circuiting. Electricians are examining cabling up to 70 years old | to trace the problem; they spent Tuesday night replacing worn | equipment on the Hainault loop. The earlier failure which stranded | 29 trains in tunnels for up to three hours was caused by burn-outs | elsewhere; two damaged 22,000 volt cables at Mile End and a back-up | supply have been fixed only for the system to fail again. LUL has | warned that because of the intermittent failures the problem is | difficult to trace and part of the Central Line may remain closed | until Monday.
| [Tue] 30.11.93 - Central Line services should be normal today after | a "sleuthing" exercise traced the main electrical fault to 56-year- | old burned cabling at Lots Road power station; random failures | lasting up to 7 hours accounted for most of the week-long period | of delays for travellers. Prof. Brian Mellitt, LUL Engineering | Director, has said that at least 35% of the power cabling should | have been replaced 15 years ago. LUL estimates that the failures | cost £2 million in lost revenue, compensation claims, and paying | for 24-hour engineering work.

Thanks Dstock7080. If I read that correctly, the "overnight" restriction only applies to whistle boards?

It's in the Rule book, and elsewhere as said. When I learnt it (70s)it was in section 11 of the appendix to the Rule book. There was a whole range of codes using long or short whistles, e.g. four long to call a car examiner. Trains were required to whistle leaving the mouth of a tube tunnel (to warn track workers), and when approaching a platform at which the train would not stop (alerts passengers and track workers beyond). There were no time limits set other than "motor men should not make more frequent use of the whistle than is absolutely necessary for safe and efficient working in compliance with the rules and regulations" so as to "avoid annoyance to residents in the neighbourhood of the railway". Someone with current knowledge may know the current details, but I'm sure the basic tenets still apply.

It's a rusty rail move. It then runs to Liverpool Street, into the sidings and then onto Holborn, then into British Museum siding. None of these sidings had regular timetabled use, so this one timetables train ensures that they get visited at least once a week. However, the sidings may get used in times of service disruption, but this is never guaranteed, hence the Sunday morning train. What is quite odd is that other locations such as Bethnal Green crossover and Queensway crossover don't get similar rusty rail moves. I imagine the nature of the track circuits at such crossovers mean that some part of a car is always on the shiny part and that a whole car couldn't "disappear".....

I'm sure piccboy is correct, it was the same on 62TS, blind had options for Holborn, TCR, Bethnal Green, Queensway, anywhere where a cross-over enables the service to be truncated.

The latest (March) CHT newsletter has a good write-up on the testing, but also says "we still have some way to go before (the unit) is once again ready to carry passengers......." Still, it's a lot closer to that than their 62TS set!

Trains are being shown as running WB as far as Holborn during the current industrial action, presumably reversing at British Museum siding? Seems a random place to truncate the service?

the pressure actually drops in the car as the air is forced to accelerate around it, down the sides, over the roof, and under the floor. The effect lasts a good way into the tunnel until everything equalises out. I'm sure there was a speed restriction at least part way down the ramp at Leyton in the days of 62TS, but I agree it was usually taken with gusto, great fun as a kid! I used to sit behind the J door bulkhead for maximum effect!

Interesting thread....
Lying awake at my Grandparents near Newbury Park station, listening to the clanking of the coal trains being shunted
Running into my parent's room at said house having been awakened by the first service train of the day, and demanding to be taken for a ride on the trains...(about 5.30 am?)
Getting my Mum to take me to see the mysterious "West Ruislip", just to see what was there, Standard stock days ( and being slightly disappointed at what I saw!!)
Travelling WB in the morning rush on a very full train of Standard stock with my Grandad, the train would stop with a huge jerk at each station, and then set off with much jerking and clattering from the contactors. Also the way the compressor would noticeably slow down as the train accelerated, voltage drop I guess.
Waiting with my Mum at Gants Hill for my first ever ride on a "silver" train. I think there were only very few 59TS running that day, we waited hours as train after train of "dirty old red ones" came and went, until we took the grand journey of one stop back to Newbury Park in fluorescently lit splendour!! (in hindsight this was probably called "how to keep a small boy amused on a wet Sunday afternoon!)
Catching an (eight-car?) train of 1960TS from Newbury Park WB to Leytonstone, and it stopping just into the tunnel West of NP to do a "Drico" check, as per the rulebook. Sitting as always in the RH seat behind the J door bulkhead I could see and hear it all. It was a Sunday, I recall. Must have been before the cab doors were blanked off for ATO, I guess.
Peering through the frosted windows of the prototype ATO 60TS DM with the front bay out of use to the public, trying to understand how it all worked.
Rushing down the gradient from Leyton WB and launching into the tunnel, ears popping with the pressure drop in the front car (and the window drop-lights being sucked shut with a loud clatter). Almost like a fairground ride........
Like Superteacher, I loved the spirited ride WB from Stratford, with the maximum mph occurring just as the white circles for the Old Ford fan shaft were passed (more ear-popping!)
happy days

as Dstock says, they operate at main line pressure, but they also need quite a high flow rate to get them to sound, as I have discovered in the garden! I use a DIY type compressor to charge the main and train lines, and blowing the whistle is the fastest way to discharge the lot....Assuming you will use steam from your loco you may need to modify the whistle by reducing the size of the "hole" or you might rapidly have a static exhibit!

There's a description and a picture in this book. Basically they used 13ft diameter cast iron rings bolted together to form the shaft lowered onto the riverbed. By excavating through the middle, the shaft was sunk down to the depth of the tunnels, presumably adding to the top as they went. Pump the water out and you have a cofferdam from which to work. A brick structure was constructed at the bottom with four exits from which the two bores in each direction were commenced. The river was chosen as a suitable place from which to remove the spoil, the streets either side of the river proving impossible to use.

my WTT 27 shows the eastbound trip as train 20 ex Ealing Broadway, in service to Liverpool St 1331, then empty to Bethnal Green, entrain children there and Mile End, then non-stop to Fairlop. I guess the children must have had a sleepover, looking at the timings....

I seemed to recall it being weekly, but my copy of WTT 27 Oct 64 shows it as daily. Clearly marked as Special. Not sure what this trip was for, as WB departed Fairlop at 11.42 depositing children at Bethnal Green and Mile End around 12.05. Opposite direction departed Bethnal Green at 13.34, picking up at Mile End, then non stop to Fairlop arriving about 14.00. Perhaps it became weekly later on? The trains to Fairlop were used to transport children from ILEA schools that had no sports fields to the Oakfield Playing Field, next door to what is now the Redbridge Sports Centre (IG6 3HD). Oakfield is now under threat of redevelopment by Redbridge Council and I would be interested to hear from users of the site who can recount its history. Please use PM if you prefer. That makes sense, but aren't the timings back to front then? If kids returned from Fairlop at 11.42, how did they get there? (unless I am missing something?)

At one time "Special" was used when picking up a school group at Bethnal Green and running non stop to fairlop, I think this was a once a week run, Thursdays if memory serves. The train was then stabled at Hainault. I seemed to recall it being weekly, but my copy of WTT 27 Oct 64 shows it as daily. Clearly marked as Special. Not sure what this trip was for, as WB departed Fairlop at 11.42 depositing children at Bethnal Green and Mile End around 12.05.
