The signaller would have a lot of explaining to do as I doubt it would be that easily to accidentally send a train along the connection  |

Yeah, but what would happen to the train?

I assume an emergency brake application would happen as it lost codes from the automatic signalling and by then the driver would probably know, and get a WDM back into Baker Street, or if they'd gone too far they might go up the Bakerloo a bit to turn round and come back - which would be an interesting ride for the passengers!

A very very interesting photograph too if it happens! I doubt an emg application would happen if its in tripcock mode

I'm no expert so I don't know what would happen and how the train a) deals with moving from automatic to tripcock as it does now b) deals with suddenly losing the automatic codes so don't take any of that as expert advice! |

Ive got a vague idea of what happens when it loses codes, I think an alarm goes off and the brakes are applied automatically.

Yes, any train on any of the ATP/ATO lines will slam down the anchors if it loses safety codes.
Makes one wonder whether a 96ts can fit in the loading gauge of the Lakerboo

Where were the sharp curves which made longer carriage stock like the 73ts not fit?

I recall that various 'adjustments' had to be made to things in tunnels in order to ensure that the 73ts would fit on the Piccadilly line without clonking anything!
I think that the sharpest curves on that line are those between South Kensington and Brompton Road (closed station).

From driving the BVE Piccadilly line, it seems sharper than the BVE Bakerloo's bends!

Track Recording Car I assume, the 73ts trailer for such purpose hauled by 1960 DMs.
The trailers and UNDM cars are shorter than DM on the 73, mind...

I suppose the eliminates the problem of 96ts not fitting down there, as I heard they were a tad shorter than the 73ts DM's

No the 95/96 stock cars are longer than the 73s.

Someone on here reffered to the problems experienced during the 73ts introduction. Was it TP or reg?
I've got a feeling that at one point the 83ts was allowed on the bakerloo, excepting London Road Depot.
It must be remembered that at one point it was considered impossible for anything longer than 53' to fit on the central, bakerloo and northern

I think that the sharpest curves on that line are those between South Kensington and Brompton Road (closed station). Yep but it wasn't only the Picc that required 'adjustments to take new stock', platforms had to be lowered on the Northern line by a few inches, Hampstead was one such site as I recall. my recollection is that platforms were lowered by 4-6 inches where necessary. As for Knightsbridge to South Kensington the curves are quite tight even now, so tight that they require check rails. Rerailing through there was quite interesting and bonding the rails was hard work as it was more than double the usual amount. That area also happens to be one of the worst places to work in the wee small hours, a veritable sweatbox. |
