The rolling programme is dead: long live the rolling programme! Somebody tell HM Treasury.
Full Midland Main Line electrification “could be shelved to pay for HS2” headlined Modern Railways magazine (Apr’2023, p9), reflecting goings on in Network Rail and the DfT. Let’s hope the they are being over- pessimistic. If not, what price electrification across the North? Two pages later the headline is the House of Commons transport committee saying government “must increase pace” of electrification in its report Fuelling the Future: motive power and connectivity. Committee chair lain Stewart MP (Con, Milton Keynes S.) strongly urged the government “to crack on with projects for electrifying train lines throughout the UK, or identify alternative lower carbon solutions where full electrification is not economically viable.” Electric trains are simple and efficient, capable of zero-carbon operation and suitable for dense passenger services and heavy freight – services with which batteries and hydrogen might never be able to cope. The hydrogen and batteries have to be manufactured and the energy has to be, converted meaning a lot more is wasted than by using renewably generated electricity directly. The report adds that hydrogen is not currently capable of producing the power needed by freight and high-speed trains. Batteries have similar limitations, have limited lifetimes in service and produce lots of greenhouse gas CO2 in manufacture. And, many of us still say, the hydrogen must be “green” not made from fossil fuels with CO2 as by-product. (Let’s not get into the argument about whether the CO2 can be buried forever.)
The government is slow to recognise the need for a rolling programme of electrification – and the benefits in terms of learning on the job and cost reductions. HM Treasury, it seems, is happy to ignore the work done by Network Rail on TDNS (traction decarbonisation network strategy), in favour of short-term financial thinking. Payback will be long term, based on lower costs of electric trains and the “sparks effect” of more people wanting to use them. TDNS of course proposed electrification of the great majority of present diesel-powered routes. In Scotland there is at least a statement of desirable outcomes. But across the UK the rolling programme seems to be “dead”. Thankfully that does not stop forward-thinking, scientifically literate bodies like the R|A (Rail Industry Association) keeping up the argument. In our Winter 2022-3 issue we reported on RIA North’s vision for a wired railway from Carlisle to Corby, Sunderland to Warrington with the Calder Valley line listed among top priorities. Now the RIA has launched RailDecarb23 calling for – yes, you guessed it – a rolling programme of cost- effective wiring, fleet orders for low-carbon rolling stock and incentives for suppliers to get on board. There is 2-side information sheet summarising the arguments (link: Rail Electrification:p The Facts – Campaigns (riagb.org.uk)).
Meanwhile a practically brand-new line is being built between Oxford and Milton Keynes without electrification. They will end up wiring it later. It’s a cliche, but you couldn’t make it up. – JSW
