RE: Northern Rail
There is several theories as to why these units keep on failing

1) Before entering service up north, they were fitted with new "traction cards" which is a computer that controls the application of power to the motors

2) Poor driving techniques from Northern Drivers due to unfamiliarity and poor management of the training. There has been many different people all stating the "correct" way to notch up power. Notching straight from 0 - 4 damages the motors and can cause flashover.

3) Maintenance staff unfamiliarity with the units

This list is not exhaustive as there is many other theories and some of these are more credible than others but all will probably be contributory factors.
