That's because the core electrified network isn't completed yet, meaning that the network effect hasn't properly kicked in yet for freight services.
And it won't.
Modern freight operators do not want to perform loco changes.
They require too much stock to be maintained, take too long and require additional staffing - they also add reliability issues to the service due to problems with coupling and uncoupling and all that.
The only way to solve this problem is when a freight electric arrives with a diesel engine of sufficient performance that it can perform the entire trip unassisted.
At which point you have just killed the network effect for freights as well.
The majority of the Electric Spine can still be justified for non-freight services - AC conversion of the line between Basingstoke and Southhampton for improved passenger services when the equipment is life-expired;
The CBA for the 25kV conversion was based on costings that we now know are rubbish - every single 25kV project that has proceeded significantly so far has blown its budget and time scales enormously.
The project is on its last legs - which is why all the bits that are actually required to be done any time soon have been quietly transferred to other projects.
the Chiltern line will be electrified for passenger trains so Banbury to Birmingham will be done, with Oxford to Banbury as an infill with a good business case;
When will it be done?
The Electrification RUS - even at the height of NR's electrification mania - did not propose that as a scheme with a significant chance of progressing any time soon.
HS2 will rip the heart out of Chiltern's attempt to grow a London-Birmingham intercity market and return Chiltern to its late 20th Century role as a relatively low traffic commuter railway.
the various lines with local West and East Midlands services to Nuneaton will be electrified for passenger services across the region; and much of the W10/W12 gauge work needing done regardless of electrification will also enable it in future. Once these other schemes are done for their own benefits, the freight companies will be much more enthusiastic about the prospect of running electrified freight.
The Freight companies will not be interested in electrified freight until they either get Co-Co Electrodiesels with sufficiently good diesel performance to actually be useful for things other than shunting - or all the freight branches are electrified.
Neither is going to happen in the near future.
Red Diesel is just too cheap.
The Grantham-Nottingham line is short, connects two major trunk routes (one already electrified, the other will be in future) and has a good number of small town/village stations spaced frequently. It seems like quite a good candidate for electrification as an extension for East Midlands local services.
From where? To Where?
There are two trains an hour on that line, one runs to Skegness and the other one takes a tour of a bunch of unelectrified lines to get to Norwich.
Thinking it has a case is just being deliberately ignorant of reality.
Toton shuttles will likely extend beyond Derby and Nottingham and going to Grantham seems like quite a sensible choice. Bi-mode might work at a pinch but there would be quite a good case for being able to run these services with bog-standard EMUs with their lower upfront and running costs.
The 'lower upfront costs' of EMUs have been shown to be very small by the costings of the various types of IEP vehicles.
Its less than ten percent of the cost of the vehicle - and electrification already costs much more than the vehicles so the cost is almost negligible.
It's also possible that the line might see ECML services running to Nottingham once HS2 Phase 2 opens, which would further improve the case for electrification.
A handful of extra trains does not a business case make - especially since the ECML is going to be swimming in electrodiesels by then.
The northern extremities of the XC network either are already electrified or are under the control of Transport Scotland, who really want to have electric InterCity services to Aberdeen from the Central Belt.
Which is why they have determined to obtain pure diesel intercity trains?
Since the CrossCountry route from Leeds to Bristol is going to be electrified, the question is then whether electrification into Cornwall and the West Country is warranted. Electrification to Weston-super-Mare will need done for Bristol local services. Electrifying beyond would convert all long distance trains to electric-only operation.
None of these things have reached the serious proposal stage - and electric-only operation doesn't actually save much money.
A rather simplistic analysis? The Long Term Passenger Rolling Stock Strategy for the Rail Industry, Third Edition, February 2015,
http://raildeliverygroup.com/files/Publications/2015-03_long_term_passenger_rolling_stock_strategy_3rd_ed.pdf has the following comparison of the total operating costs of diesel and electric vehicles:
So this gives the total saving from electrification as £0.83+£0.21=£1.04 per vehicle-mile or 65p/vehicle-km - nearly double your estimate.
This data set is endorsed with the following statement:
TOC and ROSCO sources, for new EMU and DMU vehicles,
assuming similar annual mileages, at February 2013 price levels
The price of oil was nearly double what it is now - and diesel prices have also decreases relative to feedstocks since then thanks to the rise of the diesel car converting diesel into the dominant motor fuel product.
It also goes on to mention that leasing costs are inflated because leasors will not be sure that they will be able to lease DMUs in the long term because of electrification - this obviously does not apply to EDMU which in th worst case can be leased as a pure EMU.
The gensets required do not cost a large fraction of the cost of the train.
It also mentions that DMUs are much more expensive than EMUs - this has been disproved by the stated cost of IEP vehicles where the EDMU units are little more expensive than the EMU ones.
In other words these figures are out of date and do not acknowledge that EDMUs have changed the playing field.
Even assuming a 5% long term discount rate over the 50+ year life of the electrification infrastructure (what is your source for the 5% number?)
I found it buried in Treasury guidance years ago - and this is actually a low rate of return for commercial purposes. EDF are demanding 9% from Hinkley Point C.
Over the life of the infrastructure, there is a significant risk that the difference in operating costs between diesel and electric vehicles will increase, due to increases in the cost of oil and more severe emissions regulations - this would make the break-even lower.
Except that the cost oil is unlikely to rise enormously any time soon - and emissions figures are almost never retroactive, so this will be locked in for the several decade life of the train.
And that is before taking account of the environmental benefits of electrification and any additional farebox revenue generated by the "sparks effect" of a quicker/more frequent service.
Except this is not the era where EMUs were replacing ancient DMUs with mechanical transmissions or even loco hauled trains.
The Voyagers and Class 185s eliminated the supposed EMU performance advantage - and we are already hard up against the limitations of the infrastructure in many cases.
Sorry that I can't join in with the numbers, my RSSB account is causing some trouble and I've not been able to get a copy of the traction energy metrics data.
They took them down a while back - it has become very difficult to get hold of this stuff recently. I wonder if they are attempting to pay-wall the lot.
The actual cost of running trains supports electrification, it's fairly clear cut, and the vast majority of Network Rail managers want a reliable electrification system
It might be reliable, but what they have created is an electrification system that is
so expensive that it will never get built.
but the real driver for electrification in the next three to four control periods will be NOx emissions and the impact on public health.
NOx from trains is fairly negligible compared to cars - and modern engines will likely have selective catalytic reduction and other technologies that will drastically reduce the size of the emissions.
We absolutely cannot afford to have polluting diesel engines sitting idling and accelerating away from stations like Edinburgh Waverley, as they do all day every day.
But electrodiesels would not be idling at Edinburgh Waverley - they will sit quietly with the pan up and only start the engines as they reach the end of the electrification, which will depend on what route they are taking.
Somewhere west of Haymarket.
No, I mean the end of the 1990s, like I said. See the graph at

That blip was produced by an entirely different set of circumstances to the current slump - what we have is a structural change in the oil market and disintegration of OPEC.
This is not caused by some sort of financial crisis in Asia (although that is now happening as well).
Is that the best you can manage? Running a few trains up and down a factory siding? Hardly typical of other projects we have seen.
Just demonstrates that not all projects have magical explosive growth in demand just because this is Britain and we hate trains and bias the calculations or whatever.
To me what is being done is a sensible industrial strategy. Start with a cheaper investment, prove you have the business to sustain it (not least the products it assembles are good), then increase capacity / capability. At the point Hitachi believe they have enough ongoing business to make a capital investment of their own to expand Newton Aycliffe because it is cheaper to do more there vs make & transport from Japan then they will. If a local supplier thinks they have a good chance of ongoing business they can have the confidence to invest to be a better option for being a supplier than the current Japanese one.
It's how most businesses will enter a market - toe in the water, 'small' investment to reduce some costs (and in this case no doubt get the business), success, build up local capability (skills in house and in supply chain etc...), another local investment as cost reduction vs shipping in parts / full units from elswewhere and/or to add global capacity as orders go up.
International shipping is so cheap now that that will never be the case.
