HS2 railway

We would all agree that an express link fro London to Birmingham and Manchester would be of great benefit BUT do we have to electrify the entire length of track or just the parts inside city boundaries. 

We can half the construction/infrastructure cost if we use diesel electric trains cross country and convert to electric only inside the city. 

This is environmentally friendly as power stations are only 60% efficient at best and mostly use gas at normal/peak times anyway; isn't it ??

    It is a reasonable question, ditto for electric cars. For the UK rail network this is a good document to explain why electrification is a Good Thing: https://www.bathnes.gov.uk/sites/default/files/sitedocuments/Planning-and-Building-Control/Planning/nr_a_guide_to_overhead_electrification.pdf


    If that link doesn't work try Googling* 132787-ALB-GUN-EOH-000001 (unfortunately I can't find the original source of this report)

    (* Other search engines are available Relaxed)


    Re the the first half of your first sentence: actually no, not everyone here or elsewhere would agree with this. It is perfectly possible to make arguments that the investment could be better made elsewhere. But for professional reasons I'm sadly not going to discuss that further, or express a personal opinion, on an open forum - otherwise I'll get accused of bias one way or the other!


    Although I'm always happy to keep suggesting that the Greater West Electrification programme should be carried on down to Plymouth ? With the diesels from Plymouth to Gunnislake replaced with steam ? Although to retain my environmental credentials I will admit that we do need to find a low CO2 approach to firing steam engines first ...


    Thanks,
