Line closure Autumn 2017

BTR?

from memory there is no ballast in the sheds

Think Bakerloo through roads is more likely

You can clearly see ballast in the picture for the North Sheds
Never heard the term Bakerloo through roads

Piccadilly Circus has a crossover why can not trains use it ?

The bit that got me was the replacement bus service advertised... I can't see the point of it, unless theres something else I'm missing?

Apologies for that blatant error, Ive heard some operators use that unofficial term, also know for a fact that some of the older operators still refer to the Watford DC as the Harlequin line back from the days of NSE.

This is quite correct with a few notes:-

The South to North manoeuvre the train has to stop at the advanced stopping mark to clear the points.

The North to South manoeuvre would require a train to detrain (remove all passengers from the train), go up to the limit of shunt (marker to show where to stop for a reversing manoeuvre), shut down (traditional stock, air has to be destroyed), driver change ends liven up cab (replenish air), negotiate crossover and fully berth train before the next train can arrive at the Northbound platform as the stopping position for trains on the northbound is too near the crossover and would foul the crossover (but not the points). To add even further delay to this, there is a strict 5mph speed limit on this crossover. In all, not a practical place to run a service with North to South turning.

Video evidence of that very move caught on camera.

Also it is no longer 21st October it is 28th and 29th October that it is closed.

Is the Jubilee partly closing on both occasions between Wembley Park and Waterloo for 3-4 hours simply to allow engineering trains through?

Interesting that the works will carry over to Monday morning:

So it seems that trains will be reversing north to south at Piccadilly Circus - very rare indeed!

EDIT: The Monday morning issue has only just been announced, so clearly it was orginally planned to resume a full service from start of traffic. What’s happened?
And if it turns out that more time is needed, surely it would be less disruptive to close the line after the Friday pm peak, rather than disrupt the busy Monday am peak?

Will also require a physical barrier at Baker St due to the close proximity to the Jubilee

There is no physical barrier during night tube if you have to work there in an emergency you will need traffic hours protection
The last time there was a bakeloo closure with the jubilee running They erected a plastic sheet to form a physical barrier between the two lines
