Contentious headline, obviously the answer is yes. However.. Some older friends in the pub were discussing that there used to be a Bolton to Manchester Express in the days of steam which took 18 minutes to get in. At the time it would be to a station that no longer exists, but the closest now would be Victoria. There seems to be no such thing as a train which goes directly from Bolton to a main Manchester station, or the reverse. Technically there is the Manchester Airport to Glasgow train, which calls at MAN, MCO, then BON to pickup only. The time between Manchester Piccadilly and Bolton is.. 18 minutes. So, over fifty years and no improvement despite all the electrification! However, that stops at an additional station, and the time at Bolton is obviously the departure time so straight away modern Diesel/Electric trains are faster. How much faster? How quick could a direct train be if someone wanted to run it?
