What is the single white line parking restriction?

Hi - did a quick google and couldn't find the answer. Thought I could park there (everyone else does), but got a PCN (station side of Melbourne Grove). Thanks. M

aren't they usually in front of some sort of access, like someones off street parking for example?

the Keep Clear must apply to the whole length of the white line
