At the eastern end of the line, the 'rail adhesion train' is working very hard... It seems to be going backwards and forwards continuously...
I wondered
(1) what it actually does/how it works?
(2) how it interacts with the signalling system?

It has Central Line ATP fitted to it, normal 92TS speedo and Master Control switch and all that.
It is literally a tank which is filled up at the depot, it has a pump and a pipe. The pipe goes down to about 2 inches from rail level. When you want sandite on you put the pump on.

what is sandite?
Is the rail adhesion train used more now because of pressure to avoid delays due to 'leaves on the rails' etc?
I've never seen it so much... unless i'm just paying more attention to it!
I'm sure when it left the platform at woodford I saw the driver pushing down the dead mans handle?

@auxsetreq; You deleted your original post, because it featured 'a secret ingredient'
But at least the sandite prevents delays. (and it doesn't feature 'the secret ingredient')

(and it doesn't feature 'the secret ingredient') The *secret Ingredient* was well supplemented tonight. At least three were fed in by the burly men. And as the *secret ingredient* was bulked out by KFC and Subway, extra adhesion is guaranteed............ |

I was born and brought up in a high rise block standing right next to the busy South Coast line. Can't say we ever noticed them. I now live under the flightpath to an RAF base - Can't say I ever really notice the aircraft movement. |

Last year my student accommodation was between the DLR and City Airport. This year I'm a little further away from both, but not by much. When outside or with the window open, you notice the airport most of the time and the DLR sometimes. With the windows shut I notice some aircraft but only very occasionally the DLR.

You get used to noise pretty quickly. I grew up half a mile from a motorway, 7 miles straight out from the end of one of the runways at the local commercial airport, and 4 miles from a USAF base (and under the path that the fighter jets would use when practicing touch-and-go landings, if the runway that pointed my way at the airport wasn't in use.)
My father likes to tell a story from when I was four and my sister was two, and we had some family come to visit. A fighter jet passed over, at a fairly low altitude even by their usual standards. The visitors looked worried, but my sister and I just kept on with our breakfast and when someone asked what that sound was, I replied "F-4 Phantom" rather nonchalantly.
From the front door of my student housing at uni, you could see five level crossings over two different rail lines and a chord between them, all within about half a mile. When I moved away, I noticed the absence of train horns at all hours.

Thats nout! Don't anyone realise how loud't is inside t' brown paper bag in t' middle of t' road?
Actually my secondary was by the tracks at Ickenham. The classrooms right against the boundary were impossible to teach in especially during the summer when the large windows would be wide open. You just waited for it to pass, and if another train came a few seconds after the first one passed we giggled a bit as the teacher got exasperated.

I nearly went to that school, instead I go to one where you get a great view of the Central and Chiltern Main Line! |

West Ruislip area. (even more obvious when looking at your profile) => probably Ruislip Gardens.

Concentrating on my work? I can't when they boot me out the lessons..so off to the Central Line tracks it is.
As to the noise..noticeable, enough to make lessons in one building momentarily pause, but that's it.

I went to a school very close to the Central, that was many, many years ago. Now when I watch the Central Line dvd I always make a point of telling anyone within ear shot (who cared to listen  "that's the school I attended, St Barnabas High School" even though you can not see much, if any of it. Little did I know then that I would actually be working on those trains. |
