In this months Modern Railways it says the Met is going to get Citiflo 650

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.

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

Chiltern.

No it doesn't, it says that the CityFlo infrastructure will also talk to the
Selcab ATP system fitted to Chiltern units and that line side signals will be
retained for the section from Harrow to Amersham. Both systems will be operable.

The S stock will only be fitted with the new CityFlo hardware.- Hide quoted text -

So TfL are continuing to install non-standard equipment. This is to
be expected I suppose.

Despite a strong dislike the UK's involvement with the EU; standards
are never a bad thing.
