What others can the team suggest?

The silver-painted glass tubes used to stop big trains from going into
little tunnels, visible from the north end of Finchley Road station. There
is also a set near Barons Court, but I don't think they can be readily seen
from any station.

I'm sure if you look West from Barons Court platform, you will be able
to see them.

There is also a set just after Hounslow Central on the westbound Picc,
although I'm not sure the last time a big train tried to go that far
west.
