If ATW are loaded then their profits go to Arriva shareholders, such is the benfeit of privatisation! Not that I think they are mind you...!
We all have our own ideas about where what little money there is should be spent. In my area (Carmarthenshire) people want to see an hourly fast service to Cardiff avoiding Swansea, plus an hourly service to Cardiff via Swansea, the reinstatement of double track from Cockett to Llandeilo Jct and increases in the length of peak time trains.
In the South Wales valleys they want faster services, more frequent trains to Maesteg and via the Vale of Glamorgan, new stations in Gwent, and local trains to serve them.
I'd love to see all these improvements take place, as they would be very beneficial for the areas concerned. As would redoubling Wrexham to Chester, a 4th HoW train and improvements to the Cambrian Coast. Unfortuantely, it ain't all going to happen in the next few years!
