Default 1928 equipment causing commuter misery at Edgware Road Tube

What has failed a fair few times is the new electric points at Praed

Interesting to know. An earlier poster said that it may be new
equipment which is more prone to failure.

I am reminded of the axle counters around the Severn Tunnel which
couldn't cope with sunshine, leading to repeated failures and
eventually a crash which appears to have been caused by the axle
counters being reset without proper precautions (though this cannot
be concluded as the witch-hunt atmosphere of the time (lessened but
not totally gone these days I gather) meant that people are not
likely to admit to mistakes).

Obviously old signalling equipment could and can be affected by the
sun too, but rodding runs have ways of dealing with this and wire
adjusters are provided for signals.
