Can you think of any examples of areas with a North, South, East or West prefix that don't have an opposite number? By that I mean places with the prefix "East" that don't have a namesake with the prefix "West" or vice versa, or with the prefix "North" where no area with the same name but prefixed "South" exists or vice versa.
There are lots of examples of stations with a North, South, East or West prefix that don't have an opposite number, but that doesn't necessarily mean no area with that name exists. I mean actual places that don't have a geographic opposite number as such.
For example, there is East Sheen between Barnes and Richmond, west London (historically Surrey) but AFAIK there's no such place as West Sheen. Likewise, the next station after Richmond going towards Clapham Junction is North Sheen but I'm not aware of an area called South Sheen.
