In the shoulder peaks, there are semi-fast GN services from King's Cross to Welwyn Garden City (WGC) which stop at Finsbury Park, New Southgate, Oakleigh Park, New Barnet, Potters Bar, Hatfield and WGC. However, there are no such services going the other way, oddly.
Are there any other UK rail services which behave this way?
