With hindsight, the 1983 stock cars should have been moved onto the Bakerloo Line, enabling the 1972's to be scrapped. It seemed a waste to scrap 32 trains that were only about fifteen years old at that time.

The current Bakerloo timetable (from 8/12/13) requires 32 trains for peak service (-1 due to damaged Stock), there were only 31½ '83 Stock trains. |

It seemed a waste to scrap 32 trains that were only about fifteen years old at that time. The 83 Stock would probably have been too long to negotiate the tight curves on the Bakerloo line, and as DStock7080 already mentioned, there'd be a lack of trains. |

Not to mention all the problems that were a key decision in getting rid of them in the first place: The single doors & the poor reliability of various bits of equipment to mention a couple

Perhaps someone with more technical knowledge can advise, but my understanding is that 72T/S were the last "traditional" stock - i.e. with westinghouse brake etc - whilst the 73T/S was somewhat revolutionary. Might it be easier to keep the former in service as it's simpler to maintain?

The four car came over with the three car unit that suffered front end damage at Stonebridge Park Depot. That is going to be repaired using the cab front off a DM car recovered from open storage at Hainault Depot.

I know for a fact that the service brakes on a 72 and 73 only have few very minor differences (one is metric, one is imperial). Not sure about any other equipment. |

I thought that the 73TS used westcode brakes, or were these introduced with the D78 stock. I'd have thought that the 72TS was most like the C stock in braking equipment, which as far as I am aware didn't use westcode, but had an EP brake with a westinghouse as their failsafe. Could you clarify the difference as a quick check on tubeprunes old website (I get a 404 error for the 73TS page on the new website if you read this) says that the 73TS have a westcode EP brake, whilst the 72TS have an EP brake of unspecified origin, which I assume was a generic system. They would be similar in basic function, but no doubt they would have some differences in how they carry out their Job (use of train wires &c.) |

Correct, 73TS does have the 7 step valve westcode brake so in that respect is like D78 and hence very different to 72TS. The two that were quite similar were 72TS Mk1 and 72TS Mk2. And I seem to recall imperial/metric was one of the differences and even then some parts are essentially interchangeable. Most 72 Mk1 got scrapped when the NL 95TS came in. A few cars have been used to augment the Bakerloo fleet or replace damaged cars I think.

For the brief time I was working on overhauling brakes for both 72 and 73, it was explained to me how both stocks used the same brakes (I may be mistaken however). This is one of the cylinders of either the 72 or 73. I have another image of it completely built, but its so blurry I would be embarrassed to post it   |

If anyone could photos of the work in progress that would be great. I wonder how much of the old cab can be reused?

Thanks for the pic @luacton! I'm sure the rest of us are dying to see more, even if they are more 'impressionist' in style  |

I'm sure the rest of us are dying to see more, even if they are more 'impressionist' in style I also have a pic of a 72 tripcock I was rebuilding but would not be able to id it from the others I did near the same time. I think its the same type as the 60 Just found a pic.  |

Will the refurbishment of the 72's include a deep clean,renewal of the seating and CCTV on trains for security and Driver door closure?

Given the age of these trains maybe Queens Park Bakerloo Line station platforms should be renamed Jurassic Park!

I recall hearing of calamities at both Piccadilly Circus and Harrow in the mid-nineties, so it's likely one or both of them two

The Harrow incident involved a 313 and damage was more severe.

The 313 was Kensal Green in 1986. The one at Harrow was 3539 failing to stop at the end of the siding and Piccadilly was unit 3249.

I will check and get back - it won't be for a week though. Got a feeling it might have been both at separate incidents. Watch this space ...
