I have discovered some ridiculous disjointed thinking by the Government yet again, to do with trains. Most of the length of the main lines, east and west coast to Scotland included, are electrified, but for some reason the Gov. decided that certain lengths would not be electrified, so there are gaps. This means that every electric train has to have a supplementary diesel engine to get it through those lengths of lines, with all the accompanying weight of engine and fuel involved.
The most ridiculous one seems to be Bath, where it is the Council which has refused planning permission for the line to be electrified through the city, so the electric trains run up to the suburbs, then they change power to diesel to get into the station and out again, then once out of the city they go electric again. So diesel fumes are polluting the city unnecessarily
