Not had chance to read the full article in Buses mag, but I have noticed Alex Hornby stating that Cityzap is not intended as a competitor for NX and he hopes it keeps 100% of its passengers - which makes my ask again why it stops at exactly he same "middle of nowhere" stop on Broadway as NatEx?
Presumably the Broadway and Ainley Top stops mean that the whole CityZap service has less than 15 miles between stops, and so BSOG can be claimed. National Express can also claim BSOG between Broadway and Ordsall.
