   • 2019 October 23, Rail, pages 22, 23:

     The rail orbital routes outside of the M25 and South Coast are challenging. The corridors aren't particularly reliable, and in some places they don't exist. [...] But the reliability and journey times, particularly on the orbital routes: one train an hour from Gatwick Airport to Reading? Surely we can do better than that?
