UK train driver discovers danger of stalling a train in Peru
Train driver Simon Davies discovered the worrying consequences of stalling a train on a Peru mountainside, when he swapped the London to Manchester Pendolina for one of the highest and steepest railway lines on earth.
Mining is the life blood of Peru and every day trains carry thousands of tons of metal ores down from huge mines in the high Andes.
Coached by some of the toughest train drivers in the world, Simon finds that cutting the train in half is one solution to a stalled train.
