And Northern couldn't have ordered the 195s, West Midlands Trains couldn't have ordered the 196s and Eversholt wouldn't be able to go ahead with their planned order for 10 hydrogen Aventras unless they can easily have a pantograph added.
Decarbonisation isn't idealism, it's essential. And the extent of electrification recommended by Network Rail's decarbonisation strategy would make a pantograph (or 3rd rail compatiblity) mandatory for virtually the entire fleet. If we are where we should be in electrification terms by 2050 the only units that could get by without would be:
- Thames Valley branches (DCBMU) - 4 diagrams
- Cornish Branches (DCBMU) - 5 diagrams
- Wrexham Central - Bidston (DCBMU) - 4 diagrams
Plus maybe:
- Bishop Auckland and Whitby branches (DCBMU) - 5 diagrams
- Conwy Valley line (DCBMU) - 1 or 2 diagrams
- Ebbw Vale line (DCBMU) - 5 diagrams
- Bittern Line, Wherry Lines and Ipswich-Lowestoft (HFCMU) - 15 diagrams
That adds up to just 40 diagrams across the whole of Great Britain that hardly if ever spend much time under the wires. Take away most of the 'maybes' and you're left with just 15 diagrams, that's only about 25% availability from the fleet of 58 class 195s.
And the acronyms I just made up:
DCBMU = battery unit with Dedicated Charging facilities (rather than charging using electrification infrustructure)
HFCMU = Hydrogen Fuel Cell Multiple Unit
