Yes.Will the pan reach the required height?
Is the contact wire low enough for the pans to reach?
Just a couple of inches! So that's OK then. Like the road in Australia built to connect two states across the outback - both states built their section of road to the border, but not at the same point on the border, which rendered the road rather useless.
Have management learnt from this mistake, or is it going to re-occur in the future?
Yes.
Just a couple of centimetres - See post 8236
This is no different to tweaking the pans on 2 of the 319s to do the initial channel tunnel runs (Eurotunnel has a contact wire height 24cm higher than those level crossings were meant to be and virtually identical pantographs are used in the channel tunnel).
