Fiddlers Ferry is a 2000MW coal fired power station near Warrington that today only generates from October through to April. Coal shipments have recently restarted in preparation for the 2017/2018 winter period.
The train is passing the site of Penpergwm station (closed 1958). The old station house, which is now a domestic residential property, is currently on the market for £399,950 (€500,000)!

Manchester Victoria was once a decaying rabbit warren of a station, today it's been transformed, partly by the construction of the Metrolink interchange, where the old Bury line platforms used to be. It still retains a tiled wall map of the old Lancashire & Yorkshire Railway, whose headquarters Manchester Victoria used to be.
