Class 166 Reigate to Redhill is the oddest bit of GW timetable that turns up when Class 166 is on Bright Main Line timetable ? If my memory serves ... Class 166 were pretty much GW unless we look at Class 170 ( which we are missing ? ) Regardless, a re-worked GW should extend that run to Redhill !
Yes because Reading to Gatwick (North Downs) services are booked to be Class 165 or 166. So not at all out of place as represented on BML.
