Wrong Kind of Pressure Disrupts Trains

By Peter Woodman, Transport Correspondent, PA News


Snip

“The atmospheric pressure in the c2c train area this morning was more
than twice what it was yesterday and this led to an airlock which, in
turn, led to the falling down of the pantograph which collects power
from the overhead wires.”

Is that why my ears crackled a bit this morning :-)
