When a flashing light that informs drivers of a temporary speed restriction between Euston and Kings Cross stopped working, Euston station initially tried to inform drivers via the service information board near the driver's cab.
One driver pointed to where it said, 'not to be used for safety critical information', and the line controller then insisted that a member of station staff should inform every driver of the defect in person. Far from being an unnecessary bother to drivers, most were grateful of being informed.
It may seem a hassle to occupy a member of station staff in this way, and it is difficult to spare people when staff numbers are so low anyway. But this is precisely why we need to stick to the 'rules': make the argument for more staff on the stations so people are available for unexpected situations. And we demonstrate that the union are the ones who care about safety, and provide a safe service when we are given enough staff to do our job.
