Either run it as a 24 hour or near 24 hour service, with just a few
sidings here and there to drop a few cars out of service at night;
plus a ramp down to the Central Line, and trundle off to another ramp
up to the West London tram, and go to their depots once a week for a
major clean etc?

No tram currently made would fit in the Central Line tunnels.

That, or maybe one of those very large university/medical buildings up
TCR way might fancy being rebuilt and could accomodate some sort of
fancy dual-level depot on the ground floor and basement?

There's a vacant lot at Cramer Street. It's the exact size of the tram depot
(building only) at Therapia St.

Since the distance from TCR to Marble Arch is only about 2.5 times as long
as one of the gate accesses in Schiphol, I think a series of travolators
would be a better solution, but less disabled-friendly
