It's obvious - you run a train on the other track to take the bikes
back!

Although built for two tracks, there's only one, and also massive
restoration work would be required to bring the second platform at
either end back into use.

Then that's the one the cyclists go in, silly! ;-)

I know that Seattle converted at least one tunnel, which was
originally to be for a light rail line, into a dedicated bus lane.

I've not seen, however, anything like this.

FWIW there are tooth fairies that do an amount of Boris Bike redistribution:

I'm not going to pass comment on how this would apply to a subterranean
Holborn-Aldwych cycle route because that would involve taking the idea
seriously!

It's not just the platform, it's the whole station tunnel. Add to that
the "closed" platform-tunnel at the Holborn end is significantly less
accessible than the other (which was used until closure in the 90's)

That's the bore I was referring to when I said the others were in railway
use.

What I haven't been able to establish is whether the tunnel(s) between
the two stations [Holborn and Aldwych] are two bores, or a larger bore
with two tracks in. Traditionally it would be the former.

Perhaps boring experts could comment? (see: Yellow Pages).

Only the Guardian ...

"Stretches of vacant tunnel remain at Goodge Street and Stockwell, for
example, remnants of a bizarre second world war plan to connect deep
bomb shelters into an express connection running parallel with the
Northern Line."

Ian

Are the disused Mail Rail tunnels suitable for this, or are they too small?

Too small, I would think.

Have to use recumbents.

And isn't there talk of reactivating Mail Rail for some other purpose?

A museum in one of the stops with a short theme ride in part of the
tunnel.

Definitely two bores, like the rest of the Great Northern, Piccadilly &
Brompton Railway.

In terms of usual railway work it would IMU be more a case of
de-cluttering than major reconstruction although I'm not sure if the
Holborn end was ever actually "finished off" WRT connecting the twin
tunnels to the main line as the connection at Holborn only seems to
have led to the westbound line.

Is there any chance of reactivating Holborn-Aldwych for revenue service?
Or are the lifts the main factor, killing that prospect?

They could, for example, run a crewless train in there.

You'd still have to staff Aldwych, to service minimal passenger demand.
Aldwych is near enough to Covent Garden to be redundant.
