Where have these eight trains been living for the last six years, then?

IIRC "in the wrong place" in the form of being parked in less
convenient places outwith traffic hours. Siding space has been lost at
Wembley Park because S stock is too long. That accounts for 4 or 5
trains and until recently there was at least one away at any one time
for mods.


I think some were also lost at Triangle sidings

3 trains now - 1 District & 2 C&H. was 7 when I started there.

Yes, that definitely looks a bit less crowded now.

and Hammersmith.

Too long for the sheds until alterations made ?

Google turns up some reference to Lillie Bridge now being used for
stabling S stock.

Stabling for 12 trains after Engineers were evicted to West Ruislip.
