Stock and crew changes at Edgware Road

The District controller will only be interested if the train becomes cancelled (ie, H&C took the stock but didn't replace it) or if it's coming back late/out of turn (ie, delay caused by swapping the stock over).

If a stock & crew (drivers & trains swapped) has occurred at Edgware Road and the train comes back on time, I don't suppose the District controller will be interested or even informed.

If a defect occurs west (south if you really must) of Notting Hill gate and a stock changeover is required, the District controller will make the Met controller aware and it'll be left to the Met controller to arrange it.

East of Notting Hill gate (North if it helps) of Notting Hill gate and the Met controller will deal with it by themselves - they'll only inform the District if it'll come back late or is cancelled as above.

A train coming back from Edgware Road late is an issue because it'll be out of turn through Earls Court, will cause a gap on the Wimbledon road (The District's busiest west end branch by a mile), could put the driver at risk of a late meal relief (ie, may not be able to pick up next train on time) or late finishing (costing the company money in overtime payments).......and of course the train will running late and out of turn on it's way back to Edgware Road from Wimbledon - with technically only one platform for reversing in at Edgware Road, well I'm sure you get the idea by now...

Nope, I think I understand that.
So basically, if a C&H train is delayed on the District Line controller's railway due to a problem with the train, its passengers or crew (e.g. person ill on a H&C train at Aldgate East), the District Line controller will record all the details and pass the details to the Met controller to generate the "item"? But if the delay is caused by a District Line asset (e.g. the H&C train was delayed due to a person ill on the District Line train ahead of it) the District Line controller would generate the item and just inform the Met controller of the effects (train late, out of turn, etc) and that it was caused by a District Line asset?

On my original point, it doesn't matter to the District controller that a stock and crew swap has taken place if there is no delay to the District Line service?

Colin has more or less summed it up.

The District C-stocks will generally only be changed over for defect or if the stock is required in depot. There are occasions where the stock is "used" within reformations we are carrying out - but this will normally mean the train still goes back to the District on time.

Although the District may not need to know, generally they are told even if there is no delay. After all it may have been them that requested the changeover, or it may be on their books to be changed over later that day, in which case they can remove such a request from subsequent duty hand-overs.

We will take the stock if we are suffering stock shortages. Currently the criteria is that for every 3rd stock we have missing, we are meant to take 1 District back. This helps to balance things out. It doesn't always happen. The decision is made on a day-by-day basis dependant on whatever else may be happening.

Items.

It tends to depend on whether the delay is due to infrastructure, passenger action or if it is a staff-related matter.

For instance, if District 73 is delayed at Edgware Road by a signal failure, the Met will record the item, and the paperwork will stay on our side. The event is a result of everything Met related and our staff will be dealing with the failure from start to finish., so the paperwork will be completed by them.

But if the same train is unfortunate enough to have a SPAD at Edgware Road, then the item is passed to the District. This is because the train operator's management will be District based. (Let's not get into what catergory the SPAD was, let's just say for example it was an unfortunate error. They rarely happen, but it's the simplest example I could think of).

Passenger action will be recorded by the controller on whose patch the train is on.

There are exceptions to these general guidelines, but on the whole this is how the system is operated.

One thing that often gets overlooked at the school is that an item from a controller is a "first line report." It will generally read something like: "0830 Edgware Road, W/B T73 Passenger Action Delayed Departure.." followed by the delay in minutes. It is not the controller who then gives the details of what the passenger action was. That is down to the duty manager who is handed the item to investigate. We won't just leave them hanging without any hint of what happened. If we know some of the story we will pass it on.
