Ah the Greens, those airy-fairy people who think that wind turbines can supply all of our electrical needs. Excellent idea to electrify the entire network Caroline but where are you going to get all of that electrickery from? You don't want coal fired stations because that produces too much carbon(that'll be the carbon that's locked into the coal which originated from, er, the atmosphere all of those squillions of years ago). Then there's nuclear powered stations. No, you don't want those either because, well, it's nuclear isn't it? That leaves wind turbines and wave power. So when it's calm and there's no wind and waves.......
"First Great Central West East Coast trains apologises for the cancellation of your services this morning, there's no electricity to power them because the turbines aren't turning due to a lack of wind".
Meanwhile in France the nuclear supplied electrical network continues to ensure a reliable supply for their fleet of nationalised trains.
