On the right of the screenshot you can find railway station Called Brixton as well in this case.
As subway systems mainly are underground in city centres, outskirts stations usually are overground being part of the same system. From my point of view if using Locus Theme we can see underground lines which show us subway system. Then stations shall be as much visible as possible in my opinion. It might be nice if we would differentiated Subway stations from Railway stations, specially in huge urban areas such London where using the same ticket on both systems is possible.
