Tripcocks on 165s
" The are trip cock testers at Amersham and Harrow. The Chiltern trains have to pass these OK and they are done at slow speed, even if the train is not stopping. I'm not sure what happens to the tester once the first unit has gone past, but in theory it could trigger the second units arm out of the way. Also, when the A60 stock was first introduced, they would run 4 car sets off peak, at that time all cabs I assume would have been driveable, so a similar situation to the 16/168 situation may have occurred then, i.e. the second unit potentially being tripped at speed, I assume they solved this! -- Matthew P Jones - www.amersham.org.uk My view of the Metropolitan Line www.metroland.org.uk - actually I like it Don't reply to it will not be read You can reply to knap AT Nildram dot co dot uk Except that the Chiltern units have already encountered a Tripcock fitted signal well in advance of both Amersham and Harrow as they enter the Met territory. Both of these are approached at speed. Andyh |
