Thanks to the UK taxpayer, the Government have invested over £100 billion in the railways, and a lot of that investment has gone through to rolling stock. As I have mentioned, the rolling stock is now on average under 17 years old, with a life cycle that goes to 35 to 40 years. I will give the hon. Lady a good example of where the future is bright: in the area of innovation and technology. Great Western has just completed a battery trial for a train that has covered 86 miles, with stops, on just one single charge. My hope is that as well as new orders for trains, we will find new solutions for manufacturing rolling stock that is greener than it is right now.
