I wonder why Metronet and Tubelines can't club together and have a
joint test track instead of two seperate ones at double the cost.

Does Tube Lines have a separate test track, apart from the 900m
signalling test track within Highgate depot or the fourth track at South
Ealing? As (I think) it's using a different signalling system to
Metronet, there doesn't seem to be much point in using the same test
track.

As far as new trains are concerned, I assume it'll be a few years before
new Piccadilly Line trains need testing. In contrast, Metronet has
all-new fleets coming soon for the Victoria Line and all the subsurface
lines -- a very large fleet of getting on for 2000 cars.
