I was having a chat with a GP friend of mine who holds the "but it looks so dangerous!" opinion, and had an odd moment of brain fade. I've always thought that coaster tracks were walked and checked daily, but he pointed out that it's surely impossible to do that safely every day, especially when there are no harness points obvious - how do you walk Nemesis for example? So, given I'm almost certainly wrong about that it got me thinking - how often are track walks/inspections carried out really? I know the vehicles are checked daily and there are tests, but specifically how often are walks done?
