More technical illiteracy from Midlands Connect

with 4 comments

In their response to the House of Lords Economic Affairs report ‘Rethinking HS2’, Midlands Connect claimed: “Speed is fundamental to increasing capacity. Slowing the new railway down will limit its capacity, ability to support faster and more efficient trains, and its attractiveness as an environmentally-friendly alternative to domestic air and car travel.”

Midlands Connect: 'Speed is fundamental to increasing capacity. Slowing the new railway down will limit its capacity, ability to support faster and more efficient trains, and its attractiveness as an environmentally-friendly alternative to domestic air and car travel. '

Obviously, Midlands Connect don’t understand the relationship between train speed, signalling, and capacity.

Bombardier, HS2 capacity evaluation, 2011, figure three

Yet they’re supposed to be in charge of developing the West Midlands rail network (!)

  1. Will you explain the headway graph at low speeds, please. What is causing this steep reduction in headway?

    • Without poring over the 2011 Bombardier report, it’s not immediately obvious why the left side contours are as they are. It could be a result of ‘time spent in block’, as it were.

  2. NO, Midlands Connect is not responsible for developing or running West Midlands Rail services. Be careful to get your facts right if you wish to be taken seriously when criticising others.

    • The blogpost doesn’t say Midlands Connect is responsible for developing or running ‘West Midlands Rail services’. It says they’re supposed to be in charge of developing the ‘West Midlands rail network’.
