So the thread on railway islands got me thinking about dawlish warren which is largely cut off by the Great Western Mainline. As far as I can tell the only open vehicle access to the warren runs under a rather small bridge. Cars and some vans can get under there but I'm pretty sure a lorry would not. For pedestrians there is also a footbridge and connections to the coast path.
There is also what looks like a level crossing but it doesn't show on maps and IIRC when I was last there (a few years back) it was signposted as closed and protected by locked gates.
I am pretty certain there are mobile fairground rides on the warren that would not fit under said bridge. Did they cross before the level crossing was closed? do they make exceptions to the closure if something larger needs to get on or off the warren (asside from the fairground rides I would think larger vehicles would occasionally be needed for purposes like maintaining the sea defenses).
