Ethel is, as usual, 100% correct.
However, it occurs to me that the road might not actually be a public highway anyway. (While the laws relating to some moving traffic offences apply on certain private land, parking legislation does not apply to private land).
When I worked on the railways, I ran one station and occasionally had to carry out surveys of necessary repairs at others. I was surprised to see how far Network Rail's property (which was leased to the train operator) often stretched. Many apparently 'public' roads, on the approaches to railway stations are actually private property. (At some stations, you can be on a road several hundred metres from the station buildings but still be on railway property). To make matters more confusing, Network Rail often mark them with yellow lines and kerb markings, making them appear like part of the public highway. However, the parking rules which will apply are those laid down by Network Rail and/or the train operating company. For example, if there are signs around the station stating that parking (and/or unloading) is prohibited except where otherwise indicated, those signs will apply to the roads (on Network Rail property) leading to the station, irrespective of whether there are any yellow lines or kerb markings.
