I was at Harrow earlier today and the RAT came through. Set 710 and it was made up of 5233-5234 I think. However, in recent years the RAT has been made up of 4 cars (ie with one of the trailers removed and the RAC added). I remember a few years back, the RAT was made up of 5 cars with the RAC 6036 simply added in. Is there any reason why the extra trailer is removed now? Performance based?

Undoubtedly. The RAT trailer is very heavy, and given the age and leisurely acceleration of the A stock, any weight saving that allows the RAT to run in a standard path is definitely worth the trouble.

Is this still used in place of the usual shuttle when going up to Chesham?

Does the RAT leave from platform 1 at Chalfont and leave [407] in the bay?

Does the RAT leave from platform 1 at Chalfont and leave [407] in the bay? Yes. Passengers can be conveyed on board so long as the Station Supervisor rides with the train. When other trains run to Chesham the Shuttle is cancelled (or suspended as the Traffic Circular says  ) and replaced by bus from Amersham. |

I see that sometimes 'the 1407 replaced by buses'! What other trains would use the line bar the RAT?

The TRT (Track Recording Train) also uses the line.

Also if Audio Visual Inspection train (cameras and bright lights on the front of the train) is being run this is empty due to lots of cables and computers in the saloon and is (sometimes?) staffed by Metronet Train Operators intead of LUL ones. So the only one you're likely to get a ride on is the RAT ;D ;D |

Shame- quick (slightly related) question- there are 24 double ended A stock units (I think) how many of them are A62 sets? As far as I can see they are all A60s! If true -was this to standardise parts (compressors fro example)?

What is meant by the new electric engineers locos ?
Has a firm order been placed for manufacture, if so, with whom ?

Tubelines have tested/are testing new Transmission Based Train Control systems to their current fleet. From www.mytesttrack.com/MTTBrochure2007.PDF |

The Weedkiller train also goes to Chesham.
Just to let people know what the RAT train is....its the rail adhesion train, and is similar to the sandite trains on the mainline. The top end of the Met is particularly plagued by leaves on the rails.

So when the RAT runs to Chesham, the passengers would be in the cars other than the one with all the sandite kit in, with a station supervisor milling around to check nobody touches the equipment? Isn't there space for this to happen on trains such as the TRT?
I too thought the weedkiller was a 38 stock train. However, I also thought it had packed in. Perhaps the kit has been transferred to a wagon which can be hauled by a battery loco?

It is possible, however I think the main reason is that the Track Recorder is operated by Tubeline's Operators and their licence may not cover passenger trains. Also they have limited space on the TRV, albeit with some comfy looking chairs and a cooker!. The RAT is an A Stock and has normal passenger seating, they would not be in the car with the equipment, but in the leading car (I think, I haven't read the operation document for a while  ;D ;D) |

Saw the RAT 30 minutes ago at Harrow plat 2 waiting for the signal to go to Amersham. I wonder where trailer 6232 is at the moment?

I believe that is what happened. The 38 stock weedkiller is definitely dead. As for the TRT, it is a unit of 1960 tube stock, no units of which have been used for passenger service for a few years now. So even if it had proper seats, passenger alarm etc. (which it probably doesn't) I don't know if it would be considered a currently approved passenger train. The only circumstance I can imagine passengers seeing the inside of it would be if they were desperate to detrain and the TRT happened to be the nearest available train. |

The Chalfont or Chesham Supervisor will go rather than tieing up the DMT! |

The 1938 weed killer is not dead, its in Ruislp depot awaiting disposal. ;D |
