The Liverpool to Manchester line ? the world?s first intercity railway, a remarkable feat of early Victorian engineering on which Stephenson?s Rocket triumphed in the Rainhill locomotive trials of 1829 ? is another key route, and its electrification over the next four years will also make it possible to run through-electric trains from Manchester to Glasgow and Edinburgh.
It also means Liverpool can run through-electric trains from Manchester to Glasgow and Edinburgh as well. But as usual they always miss Liverpool out.
An electric train emits around a third less carbon per passenger mile than a diesel train, and less than half as much as a private car and a quarter as much as a short-haul plane. Rail is a small proportion of total transport and, therefore, of transport emissions, but its capacity to reduce overall emissions is significant if we pursue a relentless policy of both electrification and expansion, including high-speed rail.
The passenger and operational benefits of electrification are immense. Electric trains are far quieter, more reliable, less polluting and cheaper to buy and maintain than diesel trains, and this difference is increasing over time. These main-line electrifications will pay for themselves over the medium term in reduced train and track running, leasing and maintenance costs.
By using supercapacitors to reclaim braking energy the efficiency is even greater and less CO2 emitted. The supercapacitors can be on the trackside.

How Merseyside can greatly benefit:
- It does make sense to put overhead wires on the Canada Dock Branch Line, so electric freight trains from Liverpool Docks can run on the West Coat Main Line overnight.
- Using dual-voltage pickup trains The Canada Dock Branch line can be integrated into Merseyrail serving the New Liverpool FC stadium, and stations along the way to Bootle. Anfield, Tubrook, etc.
- Lime St mainline to Bootle is possible, under Merseyrail.
- Lime St mainline to South Parkway via Mossley Hill is possible, under Merseyrail.
- Lime St mainline to St Helens/Wigan is possible under Merseyrail once the Manchester line is electrified to that point.
So, putting wires over the tracks on the Canada Dock Branch should be the first section complete, and it is being done ASAP they say. Then the section from Liverpool to St. Helens to get this section running up on Merseyrail electrics. In 2.5 years Merseyrail could be well expanded.
Branching the Waterloo Tunnel into the Northern Line will make Merseyrail sing, as Edge Hill to the Northern Line is then possible. That means St. Helens trains can get to the city centre, as can even a dual-voltage Manchester train if need be go into Central station. I doubt the Manchester train would go into Central though.
Once complete a service from the centre of Manchester can go to South Parkway for John Lennon airport. All by electrification of the Manchester Line and the Canada Dock Branch Line. All looks good, but Liverpool should insist that the Liverpool section is done first to get all stations to St. Helens onto Merseyrail and also the Canada Dock Branch Line section incorporated to get that onto Merseyrail - all done at the same time. Manchester does not have a metro so Liverpool should be the first section complete because of greater public benefits.
Supercapacitors
"China is experimenting with a new form of electric bus (capabus) that runs without powerlines using power stored in large onboard electric double-layer capacitors, which are quickly recharged whenever the electric bus stops at any bus stop (under so-called electric umbrellas), and fully charged in the terminus. A few prototypes were being tested in Shanghai in early 2005. In 2006, two commercial bus routes began to use electric double-layer capacitor buses; one of them is route 11 in Shanghai.
In 2001 and 2002, VAG, the public transport operator in Nuremberg, Germany tested a hybrid bus which uses a diesel-electric drive system with electric double-layer capacitors.
Since 2003 Mannheim Stadtbahn in Mannheim, Germany has operated an LRV (light-rail vehicle) which uses electric double-layer capacitors to store braking energy."

These supercapacitors are now so advanced they are claimed to replace a battery set and used for all electric cars reaching 400 miles range - we shall see.
