Whilst all around you are losing their heads, you must be a picture of calmness and sense in a crisis.
You must have the ability to concentrate 100% of the time when behind that control, you can't let your mind wander on the first service of the day at 4.30am or the last service at 1.30am and you can't make a mistake not even a miniscule error of judgement.
Its the same as an air traffic controller, or an airline pilot.
So much potential responsibility and equally at times very little to do.
If you have good health, can be 99.9% perfect 100% of the time and have a great memory. Apply here!
Many people will want to apply, many people will fall at a hurdle in the process resulting in only a very small trickle of quality staff making their way through the training programs and out the other side.
