I also wonder how many holding lights there are on LUL -- the only
two that I have seen are at the westbound platform at Mile End and
the westbound platform at Finchely Road.

Are there any others?

I've never heard of these before. Are they just lights or do they have
any text? What colour are they?


There is a sign mounted at the end of the westbound platform at Mile End. It
lights up when a Central Line train approaches, and I believe it says Train
Approaching, or something like that. It's mounted rather high up, but has no
real colour to it.

The holding light at Finchley Road looks similar to a tripcock testing
signal, only it displays the letter J when lit. It's located almost next to
the starter and is at about eye level.

Are either of those holding lights controlled from somewhere or do they
automatically light up when a train approaches?


I'm pretty certain they are merely automatic indicators. At peak times
the timetabling is tight, and anyway passengers won't have very long
to wait for the next train. Keeping to the timetable is the best way
of being courteous and considerate to the greatest number of people.
