Today, at West Hampstead, I boarded a train which was advertised as terminating at Finchley Road. At Finchley Road, it was detrained, and I fully expected it to return north vis the crossover. However, it headed south. There is no reversing facility south of Finchley Road until Green Park (for Charing Cross disused platforms).
So why was it detrained?I doubt it there was a defect as nothing was mentioned to that end.

Power supply issues in the Westminster area have been causing disruption since 1600hrs this afternoon, it may just be that Neasden foresaw a log jam building up and were scaling down the service in anticipation of this before short tripping trains at the very closest points in this case Green Park and Waterloo respectively.
I’ve definitely witnessed services being detrained (not during industrial action) at Baker St and Bond St in the past during service disruption.

Fair point but the train would have needed to continue to at least Green Park. If they wanted to thin the service, why not send the train back north? |

Perhaps it was going to be held for a long while between stations.

This next bit is a hunch, that crossover is set quite far back so by the time the driver switched ends and pulled away there would have had to have stopped traffic in both directions. Since the line wasn’t suspended (at least wasn’t publicised as being so) I assume some trains did struggle through, by detraining say every alternate train in situ, they could be brought back into service should the service resume without being held at the platform as there are no passengers to worry about. Don’t know wether the Jubilee has the ‘Victoria more trains than platforms’ scenario but it would explain this. |

There's gotta be a path for it on the north.
Finchley Road is quite a nice place to detrain because many passengers can get on the met using the cross platform interchange to head on to Baker Street.
We can't know for sure why Finchley Road was chosen, but if Green Park was already busy or if another train ahead of yours was gonna be detrained at Green Park as well, you wouldn't necessarily want to disgorge the passengers there.
Another possible factor, as Chris suggests, is if you get the train emptied out early you can then let it sit in the middle of a tunnel for as long as you like without all the passengers on it getting sick from the obnoxiously hot weather  |

Don’t know wether the Jubilee has the ‘Victoria more trains than platforms’ scenario 63 trains, 27 stations. I can't think of nine stations with three platforms, but there are a few sidings as well (and Charing Cross) |

But at least it has much route mileage which is above ground.

I can't think of nine stations with three platforms, but there are a few sidings as well (and Charing Cross) Peak rolling stock working for the Jubilee is 58 trains (morning and evening peak hours, fewer outside of this time). There are 57 platforms available, excluding Charing Cross. Generally there will always be at least one train in one of the North end turn back sidings (West Hampstead, Willesden Green or Wembley Park) so in theory all trains should have a platform. It wouldn't be too difficult to get the 58th train in a place to detrain if circumstances required. |

I don't know the specifics of this example but as others have pointed out Green Park reversers do sometimes detrain at other stations. This may on occasions be due to lack of available staff to help detrain, but in yesterday's case I imagine it was due to Green Park being particularly busy, with eastbound passengers from Westminster having to backtrack first and then travel east from Green Park.

It's also perhaps better for passengers to circumvent the disruption (cf the Victoria line thread), which you do by saying "Look, shiny met train, not delayed, off you go!"

Happening again today (Part Suspended between Finchley Rd and Waterloo), looks like TBTC has a headache in the NB Bond Street area, trains are reversing SB to NB from the platform at Finchley Rd this time.

The main difference this time being that the trains are actually terminating and reversing at Finchley Road. |
