What factors affect the assignment of rolling stock to train numbers (or should that be train numbers to rolling stock)? (By train numbers I mean the running numbers in the Working Time Tables, not individual car identification numbers).
I know that trains have to be serviced at regular intervals and obviously another factor is the type of rolling stock, e.g. S stock are still theoretically confined to nominated workings due to depot space and staff training considerations. But otherwise, it generally seems like a fairly free choice?

Some trains will need to end up at a depot for planned maintenance, so they will need to put on a working that will finish at a location where that can happen.

I think the question was how do you allocate a particular unit, e.g. 91001-92001, to a particular working?

Car/unit allocations would be done by Fleet not the Operations department.
As has been said, a watch is kept on vehicle mileage and units requiring attention will be worked back to main depots.
Allocations of all other units will be up to the whim of the DDM Duty Depot Manager, although care needs to be taken at some depots to keep S Stock on certain workings, D Stock on certain workings etc.
(ps. I was recently allocated a D Stock for an Edgware Road 07x working, this was soon changed after a word with the DDM)

Thanks for the help everyone Sorry hobbayne, I should have been clearer - Chris M is right in his interpretation, but that's still good information to have So how much of this information is passed on to the line controllers? They presumably need to know which units require attention and should not be reformed into, say, a Parsons Green stabler?

Running numbers can also tell other information as well. Generally the 700 range seems to be used by the test department.

I know they use a system called TOMAS to allocate the set workings with the units but don't know what it stands for

If a line controller wishes to use a midday (between the peaks) or early evening stabler to reform into something else, they will contact the depot that train is destined for and ask if it is required to be stabled as booked. The answer will then determine whether they can use it or not. It works the other way too though; depots do contact the line controller from time to time and ask if a particular train can be reformed onto a working that gets the train away early.

Indeed that is the idea in theory but the service is paramount so if the controller needs the train he takes it. When the depot needs a train urgently, if possible, it will be kept in depot as a spare.
