Could someone clarify the sleeper spacing in tube stations please? I’ve got copy of a drawing which shows 915mm, which equates to the equivalent of 20 sleepers per 60ft panel. Trying to scale from different pictures gives various results. I’m trying to plan a model and need to decide how many “pit blocks” are appropriate. Out of interest, what’s the spacing in tube tunnels, I’ve always assumed 24 to a panel equivalent but may be it’s different? Many thanks for any pointers

My only recollection of 5-lamp headcodes is that, if the middle one is lit, it's going via the Bank. On the Central Line, highly likely 😀😀

Were the standard stock wheelsets all spoked or were there some discs used? I'm assuming that the powered axles were spoked, but were the trailing axles on DMs and trailers spoked, discs, or a mixture? Looking through all the books I have, I can see some non-driven axles were definitely spoked, but others look like discs. One photo I've got looks like spokes on one truck but possibly discs on the other! Not inconceivable, I guess... Any help warmly appreciated

Were the headcodes of the standard stock used right up to their withdrawal even when mixed in with 59/62 stock or were they used as marker lights for a while?

I remember peering into it at Grange Hill, are there any pictures of it in this condition?

Don’t recall seeing and never heard of a combined controller on 60TS. I remember well the car with the sectioned off bit, the windows were “whitewashed” like when you do decorating. I used to squint through the missed bits at the edges of the window

Hi there, I'm looking for a colour photo of the platform train describers as used on the Central in the post-war period. They were grey in colour with an indicator for first and second trains, using a light box inside.
Many thanks if someone can point me towards one

The process is pretty much as neilw writes. On LU, staff responsible for Protecting Workers on the Track in Engineering Hours (PWT-EH) must observe the last train, place their 'egg box' (a Current Rail Indicating Device) on the track, wait for the current to go off at or after the published time for current switch-off (the CRID lights go out), test it still works using the test button, then go on the track to work. If the current goes off early and a recharge is needed (or there's an incident requiring current off close to the normal switch off time), they mustn't go on the track, and this usually results in a big delay to everyone working as all the PWT-EH's have to be contacted to make sure they're not on the track. Rather than placing earthing straps the re-energisation is managed by procedure; the staff concerned 'book out' with the Track Access Controllers and the PWT-EH for each group must check in at the end of the shift to confirm all their staff and equipment are clear of the track and it is safe for trains to run. Only once each group in a current section have confirmed they're off the track can the current be switched back on in the morning. In possessions it's more complicated, and this does involve the placement of shorting bars at intervals.

Could someone offer me a brief explanation of the process involved for ensuring power is off before trackwork or similar commences, please? I have some old documents (60/70's) which seem to indicate that once the substation had turned the power off in an evening it was deemed OFF and was up to the p-way workers to check this was true using a box of eggs or similar. It stayed OFF until the appropriate line clear paperwork was completed but there didn't appear to be any earthing or SCD applied. These days, are permits to work issued and is the track earthed or shorted before such permission is given? Thanks in advance.

Sorry to ask a basic question, but something has piqued my interest. Typical (disc) shunt signals turn through 45 deg in an anticlockwise direction when they show OFF. Is this or has this been universally the case, or have some cleared in the other sense?

The doors that Chris W refers to are different because they are castings not sheet metal like the body sides. Obviously a different grade of material which oxidises differently. The doors always were darker than the body panels

I'm really enjoying the articles in the latest UN about the 60 year history of the 1960TS. However, I have a memory not referred to that I can see, and that is of a car with the section between the cab and the first pair of doors closed off and full of equipment. Obviously this was some form of R&D, but I don't recall if this was for the initial ATO or something later. Anyone know the car and dates, and anyone have a photo please? Many thanks

Hi there
Has anyone got any information and/or photos about the traction current bleed resistors at the end of the traction current sections, please? We're in need of something for the Tramway Museum so any information would be helpful, thanks. Info such as current rating, resistance value, and potential suppliers (sorry for the pun....)
many thanks

Hello all
I'm doing some research on saloon heaters for my 62TS, which in turn has thrown up some queries. There are twelve heater elements per car, does anyone know the wiring configuration? I assume they are either all in series across the 630V, or are in say two strings of six. Heaters are about the only schematic I don't have, or at least I can't put my hand on. My query refers to 62TS, but I imagine evrything up to 72TS is the same.
All help greatly appreciated

I heard tell of an event on the Central, told to me in the early seventies but not sure of the incident date, but think it was 62 tube stock. Guard had the habit of closing his door along with passenger doors, holding it open with foot, watching as train went down platform, move foot, sit down. On one occasion said guard still had his weight on the foot which was on the platform, shut his door, and driver was a bit quick away. Guard fell onto platform but his door closed onto his ankle, dragging him down the platform on his bum and skittling the recently alighted passengers. He managed to get his foot out before he reached the headwall. The first the driver knew was when he stopped at next station and heard the anxious passengers banging on the inside of the unopened doors. On investigation, he discovered no guard. Guard was OK other than seriously ripped trousers! I seem to recall Marble Arch featured somewhere in the tale....

Hello everyone
Following up on this subject from last year, are P-CRIDs still in use, as I hear that they are no longer being added to the system? Any clues as to who might be knowledgeable about them, we are still investigating power indication for the Tramway Museum? Many thanks

yes, I've done it, about 20 years ago, arrived at a signal failure and was unable to make contact by radio so had to take off juice to use hand set to speak to controller. Was nervous about it but not a problem. Wires surprisingly thick and tight when handled. I did not feel any current.
I thought that the Drico telephone which clipped to the wires didn't trip the current, only the emergency phone carried in a wooden box? Or am I out of date?

the coning helps a bit but the lack of a diferential in the axle means that trains always bind to some extent on curves, can be quite noticeable sometimes and the lubrication effect of wet rails is also quite marked in reducing it

uncoupling the auto couplers also resets the tripcock(s) to the "armed" position

orienteer. Theoretically you are right, of course, but we see exactly the same effect at Crich with our trams. Using the rheostatic brake coming down the hill, if the railhead conditions are horrible, the wheels will lock, everything goes quiet, and the controller is returned to off before re-applying. I agree with you, you would think that as the wheels slow the resulting braking force must drop to zero and so they would never lock. I will ask around ......
