Hanwell is on the Great Western main line not that far from Acton where freight such as this aggregates train from the West Country is handled. There is therefore quite a lot of freight traffic through the station as this returning empty Hanson jumbo train illustrates. 59102 is the loco and the date is the 17th November 2005.
