72 Stock to Serve Until 2030's

Well it very much depends. Such rebuilds have a legitimate role to play, not only in financial terms. Sometimes construction just can't be matched in terms of quality or standard, because either the same materials are unavailable or modern rules, practices, and standards disallow it to be built new, yet accept it being brought in through 'grandfather rights'.

However, whether the 92ts or 72ts represent a physical manifestation of the ship of Theseus paradox is something of a moot point - neither is occuring because the product is good, its just because they dont have the money or the political balls to say either is knackered as bluntly as they should. Throwing good money after bad comes to mind.

By TfL's own data, the 73 stock is the better stock by far. But the 72ts is in too bad a condition, and the Bakerloo isnt gauged for the 73ts, or any other 58' stock. Neither is the Central!

No doubt in the old days some convoluted plan would have emerged! Order new trains of the 95/6 design now for the Picc, but only enough to displace as few as needed 73ts to the Bakerloo. Then, when the NTfL is finalised, order that for the Pic and the W&C, scrapp the 73ts left on the Pic, put the drains 92s on the Central and the new batch of 95/6 stock on the Jub and Northern. Then order the NTfL for the Central, then the Bakerloo.

Indeed - perhaps they will need to try the same trick with the '72 stock if it is as bad as some people say.

Going on that basis, I guess we should expect to see the first refreshed train in the spring of next year, and as I said earlier in this thread (or related thread), it wouldn't surprise me if certain bits (destination screens and PIS mainly) were nicked from the D Stock in order to help keep costs of the refresh down.

The plan at the moment is for the 72 to turn up at Acton works for a overhaul. The prototypes are being done currently I believe. Work was carried out at Stonebridge park depot to build a new road that is a ramp to get the stock up onto lowloaders to be driven to Acton.

Last time the Bakerloo was taken by rail so I am a little confused over the use of low loaders but I can only assume it due to the route they would take.

The reason they are installing a ramp from 36rd at Stonebridge Park depot, is indeed to take the cars to Acton Works by road, it may seem strange, but because the Jubilee Line is now TBTC controlled the Bakerloo Line trains are unable to cross to the Jubilee line without a whole possession of the line, which is almost impossible to achieve.

It was the same reason as some engineers trains were hauled from Ruislip over Network rail to Willesden to gain the Bakerloo line, however the Engineers trains are now able to cross from Jubilee Line to the Bakerloo Line

With more different signalling systems being installed, cross transfers of passenger stock between lines will become very rare.

The 72 stock is most likely out of gauge on many places on NR, to get clearance which would involve detailed survey and engineering clearance of any fouls, also the route access would have to be paid for and loco haulage, all shoe gear would have to be removed as well. unfortunately road now wins, as cheaper option.
For example Twyford Station on NR the platform would take all the outer sill plates off the train, as tube stock is much wider at the lower end of NR gauge,
This was found when data was obtained to attempt to bring back the Asset Inspection Train back from Eastleigh

Step boards and lower seem to be a fairly common problem, I remember it was these that caused problems for A Stock pretty much everywhere and C Stock between Barking and Upminster. NR stock doesn't seem to be exempt either, the Networkers had to be delivered with step boards removed and there are many places in South London where they're banned (e.g. leaving Wandsworth Road on the Overground towards Clapham Junction, or north of Blackfriars).

If it isn't step boards then it is the power supply...

I think that train came over under its own power in Engineering Hours as the spur hadn't been built at Stonebridge Park then.

The bit about the 442s would probably be because they were a small fleet, built in the late 80s, and to date are the only type of stock built with that sort of door mechanism. I personally would have thought the biggest problems would have been the ancient motors, from the 4-REPs, making them about 50 years old, of hard service. Its no wonder they were all combusting not that long ago

I am quite lucky to work on main different components for the underground some of which include Bakerloo equipment. Some of it really is of quite basic design, but it works. I have no doubt the Bakerloo being able to serve till 2030 as the parts I have seen have been in very good overall condition.

If only they would fit armrests and "dangly knobs", then it would be real retroland down the B'loo.

any update on this?

by seen the cars do you mean you have seen them in refurbished state?

There are 7 cars in the workshop. Their numbers:
4337
4538
3337
3438
4237
