“Crucially these are our assumptions for how rail will decarbonize. Electrification is a very mature technology in rail unlike for road vehicles. We assume 66% network electrification by 2050 and phase-out of pure diesel trains by 2040. Concerning to hear govt briefing against rail electrification”

“As you can see the key themes are electrify everything we can, and increase low carbon electricity supply in line with this. In doing this we move from an opex based energy system to a capex based one. These investments start paying back nationally through much higher efficiency by 2040 and on”

Performative decency is actually *so* important for this reason.

It tricks the 10% of ghouls into thinking that there are only 1% of ghouls.

And it makes the 30% of people that don't care one way or another follow the mostly decent crowd

Tim flagged that London Gateway (the UK’s largest container port) can’t increase its rail freight share - or decarbonise it fully - without electrifying a few short miles of branch into the port. But there is still no funding for this, so we are left with diesel locos chugging through London.
