In reply to news post, which Jack Taylor wrote on

Tonight (Monday) the 19:15 Marylebone to Aylesbury (first stop Great
Missenden) departed approx 30 secs late from Marylebone (due to the last
minute substitution of a Class 168 from an adjacent platform, as the
country-end 165 of a pair was defective, trapping in the set to form the
service). Arrived H-on-H virtually on time, crawled through the platform and
then staggered all the way to Amersham. Why? Because the buggers in Harrow
box had let out an all-stations Amersham stopper in front of it! Again.


Chiltern trains non stopping at Harrow north bound will always have to
go through at slow speed as there is a trip cock tester signal at the
end of the platform. Even if the signal is green, the train has to slow
for the trip cock to be tested. You can see a white light by the signal
which comes on as a train approaches, if the light goes out then the
train can proceed, the light only goes out when the train is pretty near
the signal, hence the requirement I guess for slow speed.
