Something no one in the media or on here seems to have mentioned is
that the only reason the drivers are noticing so many tripcock
failures is that so many of these overpaid agitators are going
through red lights! Perhaps while they're fixing the trains they should
consider getting the drivers retrained. How exactly can you miss a red
light in a slow tube train usually (on the northern line) in a dark
tunnel?
They don't have to worry about other traffic , roadside distractions,
steering etc like a bus driver but if a bus driver went through a red
light
I don't think anyone would have much time for him blaming the bus for
not putting its brakes on!
