MML Electrification: progress updates

[Nottingham59]

To what extent can nimby opposition directly push down on an electrification project?

The power to block comes from things like listed buildings consent. Like the local council did with Steventon bridge during Great Western Electrification. See here:

Steventon Bridge: Overcoming the Obstacle - Rail Engineer

Listen to this article In the complex story of the electrification of the Great Western main line, one name keeps cropping up – Steventon Bridge (issue 167, September 2018). This structure, and the problems it has caused, has been the subject of much media coverage, both technical and public...

there are some 110s for HSTs, could it not be made possible for other trains to use those speeds? What was the special ability of HSTs for them to be allowed faster?

There's a 110mph section from Wingfield Tunnel to Clay Cross, and also a bit just north of Derby. I assume other trains can use those speeds. But the point I'm making is that north of Derby, the MML is not a 125mph mainline, which would help to justify electrification.

A train requires enhanced braking to use the HST speeds. However, 22x stock are able to use HST speeds and I believe the same will be true of 810s and probably of whatever eventually replaces the Voyagers.

Better braking characteristics came with HSTs, so speed could be increased without changing existing signalling, but bear in mind that since then HST speeds also apply to many other classes, eg 220/221, 222, 80x, some older DMUs including EMR’s 158s and 170s.

First post from a local...I fear there will be a lot of trouble with the segment from Derby to Clay Cross:- the locals are currently in strong opposition to a project to build power lines through the Amber Valley and have just elected two Green councillors ……..
