In this months Modern Railways it says the Met is going to get Citiflo 650
moving block signalling in the next few years which does away with lineside
signals. Which raises a couple of questions - why didn't they just use the
same system as on the jubilee line given that the 2 lines run side by side
for a long distance, and what will happen on the uxbridge branch which is
shared with the piccadilly? Will the latter be terminated at Rayners Lane?

My Modern Railways is still awaited. This also raises the question of
the section, north of Harrow-on-the-Hill, utilized by Chiltern. One
more reason to withdraw to Moor Park I guess.

These questions are answered in the Modern Railways article

Seems an unreasonably long wait. When did they first go on the shelves
at WH Smug's? 22nd December?

He's presumably waiting for the US Mail to deliver it?

I thought it was because they had different operators under the PPP?

The signalling contract was put out to competitive tender. I assume
Thales bid with the same system as the JNP lines but did not win. We
therefore have the Cityflo system. I think one of the reasons
Bombardier won with Cityflo was the promise of minimal closures to
install the system. I think Cityflo is installed in Madrid which was
one of the places LU visited to see resignalling was done without lots
of closures.

The last I heard the 73 stock was to fitted with the necessary kit to
allow the trains to "talk" to the Cityflo system. This is essential
not just for the Uxbridge service but to be able to get through Acton
Town which is all sub surface signalling over the shared tracks. I am
not sure whether the Picc Line tracks from Acton to just east of
Barons Ct are to be equipped with Cityflo or will remain with
conventional signalling. Of course fiddling about with the 73 stock is
not without its risks if you need to touch any wires or cables.

Will that really be necessary for 73ts in revenue service, considering
that LT plans to have the EVO running in revenue service by that time?

The article says the S stock will be fitted with the ATP system used by
Chiltern.
