Periodically, in the morning (usually if there are delays in the City) Met lines from the Uxbridge branch terminate at Harrow OTH, instead of carrying on in to the city. However, these services then tend to procede from Harrow OTH southbound, towards Wembley Park, empty - with all the passengers dumped out, waiting on the next Southbound service.
I think the last instance of this happened last Thursday when the train went down the fast line after leaving everyone at the station.
I've always been intrigued as to why people get dumped out there, as opposed to being able to continue down the track to terminate at Wembley instead? (OK - selfish - I was going to Wembley that morning)

Usually when a train detrains at Harrow, a train will (or soon will be) on the adjacent platform to pick up the passengers who have got off the tip out. In a sense, that causes less disruption. It is also easier to run the empty train down the fast line to Neasden Depot and put everything else via the local line to call at all stations. If there is considerable disruption, it also makes it easier to queue up empty trains for Neasden Depot on the fast line.
It can also cause more disruption by detraining at Wembley as a train may get the signal to depot, but may still be in the process of detraining, therefore bringing both Southbound roads to a complete standstill. Sometimes it's unavoidable, but Harrow is the place of choice to detrain with minimum disruption.

Whilst I bow to your greater (and actual) experience, as a passenger it's really irritating, since every time this has happened to me, the local trains are all rammed full expecting to get onto the fast train, and *then* we got tipped out at Wembley Park anyway, and had to wait for 3 or 4 Jubilee Line trains before there was space to get on. Admittedly, if things are that bad, it's hardly likely to go smoothly whatever decisions were made, but it did lead to dangerously* full platforms at Wembley Park, when it *might* not have if the Harrow tip out didn't happen.
* seemed that way to me - however I don't know what the official definition is - and I'm not sure it was avoidable anyway...

Agreed, when I've been 'tipped out' at Wembley, the majority of people get on the (already busy) next slow train so from a customer perspective, maybe Wembley is more useful a drop-off point? However, that could be a short sighted view from a customer that just wants to get to Wembley (well, ideally... I'd not have to because I wouldn't need to work but needs must  |

If you've been detrained at Harrow and then have the misfortune to be detrained a further time at Wembley, then something was clearly wrong with the service as a whole. This would never occur during normal running. The booked detrainments at Harrow are the additional peak-hour trains being removed from service to depot. Unfortunately what can happen is that these detrainments line up with typical post-peak late-running services from the branches - hence the heavier loadings. It is also the reason why the Jubilee Line trains probably arrive heavier than usual, and there is less space to get on. Why is Harrow chosen more over Wembley? Wembley is technically a Jubilee Line station, and has less staff dedicated towards the Met side of things than Harrow. Therefore, as my colleague points out, detrainments can take longer at Wembley, and delay other southbound services. Whereas at Harrow, they can be by-passed both in the station and also between Harrow and Wembley, plus there is the added benefit that staff are dedicated towards "our" trains for a smoother detrainment. Unfortunately, we cannot run the peak-hour trains all day, so they have to be removed from service somewhere. Wherever this is done it is going to become a train that is not in service and will leave people awaiting the next available train. |
