Define “crystal clear”. I think the rule that’s been published is clear, and that the only issue is to ensure that staff recognise that reasonable needs to be interpreted in favour of the traveller.And making the rules crystal clear helps avoid such conflict.
Yet others see this in the light of the routing guide, and want precision about what can be defined as reasonable at any specific time.
Setting aside the minor point that after 30 years the routing guide never fully achieved that for planned journeys, these are fundamentally different and irreconcilable concepts of “crystal clear”.
That then leads to the question of conflict. At the point at which the timetable has gone belly up, and the route is closed, passengers are stressed. They have their own plans and commitments, and are generally focused on “how do I get to my destination”. That requires practical assistance and support when they turn to railway staff.
A doctrine that treats any form of raised voice as automatically abusive, as in the extract quoted, risks inflaming difficult situations. Staff are absolutely entitled not to be abused, but hiding behind absolute rules increases the risk of conflict and hence abuse.
Which brings us back to the concept of reasonableness. If I’m travelling from Grantham to Manchester, have a ticket routed via Doncaster and Sheffield, get to Doncaster and find the Hope Valley shut, then “reasonable” is about how I get to the destination of my journey. If I choose a revised route that gets me there, it shouldn’t matter overmuch whether I go via Leeds, change at Wakefield, or take the Penistone line - just as long as I am taking trains that will move me to that destination.
