There’s a few places on our network that require nailing it at a specific stop mark due to all doors open otherwise the back doors are on the ramp so that accuracy is most definitely required. However it’s caught a few drivers out as one day they’re driving an ASDO stock then the next all doors open stock...It makes me chuckle that the health and safety bods claim such accurate stopping at stop boards is required when there can be at least 2 metres margin of error depending on the driver's perspective of the stop board (Driver's height/seat position/whether they're leaning forwards etc.)
At some stations 2m is going to make a huge difference in whether a door lines up for a wheelchair or the onboard DOO cameras give a safe view. I really can't believe that the stop board positions are so accurately placed to factor in all the possible perspective issues. If they were they'd need to at least get the tallest and shortest medically permissible drivers allowed to be involved in the testing when they were first signed off safe.
