Maybe they can run some of the 63's (say 4 an hour) single deckers that would come over the hill, terminate or turn round at brockley rise, and stop at HOP station to then head directly up to Kings Cross. They could look at timings so the service does not clash with the P12 service (although we all know bus timetables are not always right!) Surely something like that is doable?? I think a happy medium needs to be found as the service would be a great addition to HOP's travel links.
