There is little wrong with the crossing, it just needs to be treated with the care it deserves. Trains are either slowing down for, or accelerating from, the Station at that point. A couple of years ago a dog was killed there because the gates had been left open. The very next day I was down there, a car stopped, the driver got out and opened the gates, he then drove across and carried on. I closed the gates after crossing myself. When I caught up to him I pointed out that he had left the gates. He responded that it was OK as his friend was coming over shortly!!!!
The only exceptions are the non scheduled trains which have been stabled at West Kirby. The problem of these would be resolved if they were to slow down at each crossing as well as sounding their horns.
