The energy consumed by battery freight trains increases by 5% (241-km range) because of the additional battery weight but it is still about half the energy consumed by diesel trains owing to the high efficiency of all-electric drives. After accounting for the average energy intensity of the se...
Despite its supposed efficiency, the high speed train will not make my travels any more sustainable. Passengers who switch from low speed trains to high speed trains, like I have to do now, increase energy use and carbon emissions. However, most Europeans aren’t like me. If they travel ...
Looking across the various sectors for which there are clear opportunities for natural gas to substitute for oil – specifically bunker fuel for ships, natural gas vehicles (NGVs) replacing primarily gasoline-powered light duty vehicles (LDVs), heavy duty trucks both in and ex-US, power generati...
In January, Union Pacific tested a 3.5-mile long ",monster", train, using extra locomotives to distribute power efficiently. Just what are monster trains, and how are they different from conventional...

The concept is inspired by emissions-control systems used in ground transportation vehicles. Many heavy-duty diesel trucks today house postcombustion emissions-control systems to reduce the NOx generated by engines. The researchers now propose a similar design for aviation, with an electric twist. ...
Since 2017, rail-based transport on an electric network has been a relatively low carbon dioxide emission and so-called ‘green transport’ mode, compared with other means of transport (such as planes and cars/trucks) [13]. On the other hand, rail-based primary fuel constitutes an essential...
