Yes, I can get a train up to LON at about 05.15 to get there for 07.36 for an 08.30 KX LNER train northbound...Thanks
I would have to leave the house at about 04.15 to drive to Bournemouth, or Yeovil but it is doable.
My worry is the high risk of SWR Trains reliability which is shocking - especially so for the first, and later trains of the day.
I have been messed up, cancelled, or stranded far too many times in past few years.
