Electrifying Derwent Valley Mills

Under the latest plans the Midland Main Line will be electrified.

One problem is electrifying the line through the World Heritage Site of Derwent Valley Mills.

This Google Map shows the Midland Main Line between Belper and Duffield stations.

Note.

  1. Belper with its station is at the North of the map.
  2. Duffield station is at the South of the map.

In the middle of the map the railway line disappears into Milford Tunnel.

Wikipedia says this about the portals of the tunnel.

Both portals are grade II listed, being part of the Derwent Valley Mills World Heritage Site.

I doubt that the Heritage Taliban would allow the tunnel to be electrified, as they wouldn’t want wires near the tunnels.

But between Belper and Duffield stations is only 4.2 kilometres.

This Hitachi infographic shows their Intercity Battery Hybrid Train, which I described in Hitachi Rail And Angel Trains To Create Intercity Battery Hybrid Train On TransPennine Express.

Note that the train can cover gaps of 5 km.

The Class 810 trains, that will be used by East Midlands Railways will have four diesel engines and I’m certain these trains will be able to be retrofitted to be Intercity Battery Hybrid Trains.

The electrification of the line will be discontinuous with no wires between Belper and Duffield stations.

Express trains going between Derby and Sheffield will go through the following procedure.

  • Arrive at Duffield station with a full battery, after using the electrification from Derby and the South.
  • Drop the pantograph in the area of Duffield station and switch to battery power.
  • Proceed through Milford tunnel at an appropriate speed.
  • Once under the electrification again at Belper station, they would raise the pantograph and switch to using the electrification.

The problem of electrification of Milford tunnel in the area of the World Heritage Site has been neatly side-stepped.
