Ralphchadkirk, JohnMorris et al, here's my reasoning, as it always has been....
If the priority is to ease overcrowding on the TL platforms at St Pancras, prioritise the service so that those passengers with NO ALTERNATIVE MEANS OF GETTING HOME have a chance of getting on a train. Tell those passengers with alternative means to use them. FCC loves telling people their tickets will be valid on LU and London Buses as well as SWT and Southern services. None of these are any good if you live north of the M25.
The announcements should go something along the lines of...
"Unfortunately as FCC's trains are made of digestive biscuits and NR's infrastructure is made of cardboard, we are unable to offer a service to stations within the Greater London area. Passengers wishing to travel to Kentish Town, get the Northern Line, passengers for West Hampstead, get the Jubilee Line, passengers for Cricklewood, Hendon & Mill Hill use the superb London Underground network and the fast and frequent interchanging bus routes that will speed them on they way to their home. Do not come to St Pancras. FCC will be operating 4tph service calling at only those stations where we have a complete monopoly on the service to them."
I don't see why during a time of reduced train capacity it is necessary to serve the inner-London stations at all.
I, of course and my fellow cattle have the complete option of an occasional EMT service to Luton or LA Parkway, then the option of an infrequent bus service from Luton to Bedford, then an hourly bus service from Bedford to Flitwick, but not after 6.00pm because Stagecoach can't be arsed to run any services.
Anyone trying to make a case that FCC is trying its best should give up their current job and try a career as a barrister, defending hopeless cases.
The stopping pattern should be Elstree, Radlett, St Albans, Harpenden, LA Parkway, Luton, then all stations to Bedford. It would still be full, but it would have the added benefit of faster turnaround times on the route.
