   • 2020 January 2, Graeme Pickering, “Fuelling the changes on Teesside Rails”, in Rail, pages 58–59:

     Houchen observes that Hartlepool, used by around 640,000 passengers a year, is another pinch point where changes to the station are required. Despite being on the double-track Durham Coast Line linking Teesside, Sunderland and Newcastle, it has only one through platform: "Now there are some interim solutions, but the long-term solution is a new station at Hartlepool."
