By Teynham station (near Faversham) there's a house that's just the wrong side of the tracks (literally, probably not metaphorically). It's accessed by a user-operated level crossing. I have always assumed the crossing was retained because it was a dead end, but looking on the map, the road continues and joins up with another road further along, so if you lived there, you could easily go round the long way and use the road bridge - adds a few hundred metres to the journey but I expect that is still quicker than opening and closing the gates. I don't think I've ever witnessed the crossing being used.
In fact, there's a lot more going on over that side of the tracks than I ever realised - several more properties further along the road. You learn something new every day!
There are two automated level crossings locally that I cycle over regularly, on rural lanes. I'm always slightly nervous of using them because of the completely rational fear that one day the automation will break down... on the other hand, the alternative way round in both cases would involve cycling on the A2, and I'd rather take my chances with the trains, to be honest.
