The enclosed link demonstrates how you need to keep a good lookout and keep your wits about you when working on a live railway.
This report reflects how easy it could be to injured when taking your mind of what you are doing even for a moment.
Remember that on the railway every thing is big and heavy, dirty and if it hits you it hurts.
I am glad these chaps walked away from this with minor injuries.
