This paper provides a comparison of the energy consumption and carbon emissions of rail and road vehicles for two routes. The scenarios considered are a high running speed container train, in locomotive hauled and electrical multiple unit (EMU) configuration, and a converted passenger EMU for pallets, as well as the corresponding road heavy goods vehicles. The container route is over the UK's East Coast Main Line and the pallet route is from London to the border with Scotland. The well-to-wheel 2008 and projected 2035 energy figures and carbon emissions are determined. It is demonstrated that, despite higher running speeds, a modal shift to rail reduces carbon emissions. The higher speed results in a more flexible path allocation for freight trains, enabling more attractive and flexible offers to shippers, therefore encouraging modal shift. The particular advantage of rail in hauling large volumes of cargo is highlighted, particularly if locomotives are used for traction. © IMechE 2012.
