I haven't seen this mentioned anywhere else yet, but the new signalling
system has been brought into use between High Barnet and West Finchley.
The former signals have been wrapped up, and passengers entering High
Barnet station are being amazed to see all the departures for the next
half hour shown on the PIS display (well, some of them are amazed).

I guess they're not planning on keeping the old signals as backup then?

How long does it take to remove a plastic bag?

Somewhat less than it takes to remove hundreds of them over 30 miles of line.

Spud

But they have to put something over them to show that they are out of
use. The bags in fact have the regulation diagonal white cross on them.
Since the new system is being implemented in stages, I can't really see
going back over more than one stage, and I suspect that going back might
mean more than removing the bags anyway (point motor and track-circuit
connections?)
