Those have I suspect been there since the line was originally built back
in the days when the HSE had some common sense. However I stand to be
corrected and told that they're on the new extension to the airport.
Also don't forget that the metro is overhead catenary , the tube is 4th
rail.

Yes it is mostly the airport extension, and all the stations seem to be
split with the platforms on either side of the level crossing. I stand to be
corrected but don't think there are any LC that are not at stations, and
therefore the train is always stationary with the driver able to sight the
LC before he sets off again. Of course the metro to the airport mainly runs
on an old BR line, which predates the urban sprawl. I doubt there were so
many LC then. A lot of the crossing points are over residential distributor
type roads.

Surely on LU the 4th rail would be dealt with in the same way as 3rd rail on
SR lines, it would just need a break (cable connected) in the conductor at a
LC?
