I think the major issue here is the 'decline' seen since the money tap was turned off at the very top, ie Deutsche Bahn and the ongoing saga of attempting to sell/float (don't know what the current situation is!) the Arriva group across Europe. Until this is concluded the investment is seemingly not happening and with an ageing fleet, poor reliability looms and more cuts seem to be the only way to solve it at present. If DB can find a buyer (at a price they want, which seems to be the sticking point) then you may see fresh ideas and money to spend but until that time, I personally wonder what the future holds. I hope I'm wrong but I see death by a thousand cuts coming.
