I think it's high time the Hidden rules were reviewed. There is talk about fatigue constantly in the railway industry, and yet the one thing that never changes are the shift patterns that cause that fatigue. Steadily, more and more of the responsibility for managing fatigue has been loaded onto staff, whilst there appears to be precious little desire to pass rulings that would tame such damaging workloads. With each briefing, notice or training session staff are further reminded of their obligations not to come to work tired, and yet as we see here there are scant few affected individuals who feel comfortable taking action if they are. And indeed, most are seemingly fatigued regularly. It's the elephant in the room, and Tramlink have found to their enormous cost how dangerous it can be. It's worthy of note that motorists are now being steadily encouraged to view 'driving tired' as the new drink driving, alcohol being a massive no-no on the railway. Food for thought.
It's clear that 12 hours between shifts simply isn't sufficient. When crew are being rostered little more than that bare minimum in some cases, and then have to include travelling home and back again, eating, sleeping and generally functioning as a human being within that time between finishing work and returning, the problem is glaringly obvious. Similarly, the generations old practice of completing a late shift on a Saturday night/Sunday morning, having a nominal 'day off' on Sunday and then being expected to rise again in the early hours of Monday morning, very clearly makes being properly rested a complete impossibility. This is a particular concern when the start of a week of early shifts is marked by substantial fatigue. Simple proposals such as extending the 12 hour barrier to 14 or 16 hours, grouping early and late shifts into blocks of two weeks or more rather than alternating weekly, and ensuring that late - to - early shift rotations include a barrier period of more than single day off, are long overdue for serious consideration.
