In April last year Network Rail produced a
Freight Network Study. It's mostly a wish list, with priority ratings based on various criteria.
It says almost nothing about electrification. Well, what can they assume? Anything, or nothing, if built into their plans would be a risk. So they resort to the vaguest of cop-outs: "The approach to future route electrification and upgrades will be set out in due course.".
There is a short section that lists the benefits of electric freight workings:
• Increased network capacity through enhanced performance and average speed, enabling freight market growth
• Reduction in whole industry costs
• Improvements to capacity utilisation and network efficiency
• Environmental benefits when compared to diesel traction
• Improvement in the rail freight product to end users, for example through shortened journey times
• Industry confidence in the electrification programme to invest in electric locomotives.
And these are the priority routes:
• East Suffolk Junction to Felixstowe
• Grand Junction to Nuneaton
• Nuneaton to Wigston Junctions followed by Syston Junction to Haughley Junction via Peterborough
• Electrification to Thames Gateway port
• Junction Road Junction to Carlton Road Junction in North London
• Avonmouth to Patchway, Filton and Stoke Gifford Junctions
• Castle Bromwich Junction and Water Orton West Junction to Ryecroft Junction
• Niddrie South Junction and Portobello Junction to Slateford Junction and Haymarket West Junction
• Tapton Junction to Masborough via Beighton Junction
• Beighton Junction to Woodburn Junction
• Hare Park Junction to Leeds Stourton terminal Reception line
• Stourton terminal to Whitehall Junction
But in the short term, no electrification has highest priority, and just one short link rates as medium:
4. Cross-London inc. Essex Thameside
• Infill electrification Junction Rd Junction to Carlton Rd Junction and to London Gateway port
Under "other routes" there are two:
2. Channel Tunnel
• Electric traction capability for all Channel Tunnel routes, addressing the Redhill track circuit
4. Southampton to West Midlands & West Coast Main Line
• Electrification of the diversionary route via Andover and potentially Eastleigh to Romsey
That last one comes with an assumption: "Subject to electrification capability having been delivered on the core route via Winchester and north of Basingstoke". An odd way of putting it, you might think, but having already justified that and been told to do it, they haven't been told definitely not to.
One of the advantages they do mention is electrifying more depots on electrified lines. There are also specific mentions where higher speed is needed,e.g. on the
MML» and from the Mendips.
