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.
