LT are reporting "Code Amber". All trains being stopped at platforms and
evacuated to ground level.

Just out of interest, how exactly does this work? I can't help feeling
that there are usually more trains on the system than there are
stations, and that therefore some trains get stopped between stations.

The numbers vary. The Victoria Line has a peak of 38 trains for 16
stations and 33 platforms. Overall, the current peak services (pre 7th
July) involve:

Bakerloo: 32 trains (31 in the evening peak)
Central: 72 trains
Jubilee: 51 trains (see note)
Northern: 91 trains
Piccadilly: 76 trains
Victoria: 38 trains
Waterloo & City: 4 trains

Circle + H&C: 30 trains, plus 2 standing spare
District: 77 trains (67 D stock, 10 C stock)
East London: 6 trains
Metropolitan: 45 trains, plus a half train on the Chesham shuttle

[In the morning peak, one Jubilee train comes out of service shortly
before the last of the 51 enters service.]

Do they detrain people in the tunnel and get them to walk along to a
station? Or do they hold trains in the tunnel until the train ahead has
been emptied and shunted forward?

The latter is more common, I believe.
