What I meant was that although they are very useful on the
Victoria Line and certain other lines, there are stations on the
Circle Line where the nice multiline LED displays only tell you
about one train[1], and only when it is practically in the station
anyway.

The westbound District and H&C lines at West Ham are a classic example.
You can see the train in the distance either before or at the same time
as being able to see it on the indicators. That said, my generaly
experience of the indicators is that they work well and are a handy
thing to have.
