Looks like you came off the Hartlepool Docks Branch although I have never seen a train on it for years.If I recall it has a steel gate on it.Never seen anything on the Seal Sands/Port Clarence Branch either.Regarding that relief track to the left between Hartlepool and Seaton Carew it looks really rusty but I caught a Grand Central 180 between Hartlepool and Northallerton a few Sundays back and it actually went down it.There must have been something wrong with the up main.
Concrete tunnel segments are coming out of Hartlepool docks every day for HS2. Colas are bringing an oil train off the seal sands branch a couple of times a week.
