I would just like my good old Southern Service back

.
However this time maybe it should call at the following;
Rugby, Northampton, Milton Kenyes, Watford Junction, Harrow & Wealdstone, Wembley Central *Event days only*, Clapham Junction, East Croydon, Gatwick Aiport, Hayward's Heath & Brighton. These can be every 45 mins in paths permit.
We could then have a stopper service starting from Milton Keynes, calling at the following;
Leighton Buzzard, Watford Junction, Harrow & Wealdstone, Wembley Central, Shepherd's Bush, Kensington Olympia, West Brompton, Imperial Wharf, Clapham Junction, East Croydon and Gatwick Airport.
These could be run hourly.
I've diagramed it as such so that passengers can garauntee a train going towards the West of London and beyond within 30 minutes of missing the previous one.
