Parked yesterday at Waterbeach station near Cambridge, operated by First Capital Connect. The normal ticket machine was gone, despite 'pay here' signs still in place. The only option was to pay by mobile phone, fortunately I had mine with me, but the guy following me did not. Paying by phone involves extra fees including the cost of the call. If I had not paid, would I have been protected from a fine because of the absence of the machine?
