I used the GWR service yesterday from Great Malvern all the way to Brighton. Lightly loaded from Great Malvern as far as Gloucester then it got fairly busy all the way to Brighton. Not the most comfortable experience on a 166 all that way but it's manageable in the former 1st class seating area!
From speaking to the guard, they said there were a lot of through ticket holders travelling all the way to Brighton and beyond. When we arrived at Brighton, there were a lot of elderly passengers with heavy luggage as well as many wheelchair users requiring assistance.
It's a shame to see this service go, but I suppose on any given day when there's no through train you'd have to change at Southampton etc just that the connections aren't that good. These days, it feels like everyone has to use Thameslink and go through London instead
The end of an era I suppose, Brighton loosing it's last long distance service linking the West Country and beyond...
