Isn't it four tracks from Euxton into Preston widening to six then nine tracks through the station I'm sure room can be made to ensure a fast arrival and departure.So new construction all the way to at least Preston, and there you've got the Wigan problem all over again; join the WCML south of the station and you're subject to speed restrictions for through trains, join north thereof and fast ones can't call unless they run conventional WCML all the way from Crewe.
