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 didn't notice at West Finchley, but on the driver information board at
Finchley Central is a sign "Colour light signals ahead. Don't get
tripped up!"
