Leonard Rogers provides the details The train is southbound, just coming off Dandry Mire viaduct into the station. The photo almost certainly shows the Long Meg to Widnes anhydrite train, in the same way that the photo of 92233 at the same location the following day does. Wagons on this train were often sheeted - for use in the sulphuric acid production process at Widnes the anhydrite was better kept dry.
