I believe there is a solution, its a bit Heath-Robinson but consists of a
large tanker wagon, filled with water, pulled behind each train. As the
train goes through the tunnel a very fine but copious spray of water is
pumped out behind the train. This will absorb heat from the air and reduce
the temperature. I claim the prize !!!
