Dairy House railway station

Seaton Delaval Hall is a Grade I listed country house in Northumberland, England, near the coast just north of Newcastle upon Tyne. Located between Seaton Sluice and Seaton Delaval, it was designed by Sir John Vanbrugh in 1718 for Admiral George Delaval; it is now owned by the National Trust.Since completion of the house in 1728, it has had an unfortunate history. Neither architect nor patron lived to see its completion; it then passed through a succession of heirs, being lived in only intermittently. Most damaging of all, in 1822 the central block was gutted by fire, and has remained an empty shell ever since. The 18th-century gardens of the hall are Grade II* listed on the Register of Historic Parks and Gardens.

The beam of the pit's pumping engine broke and fell down the shaft, trapping the men below. The disaster prompted a change in British law that required all collieries to have at least two independent means of escape.

Hartley is a historic village in Northumberland, England. The village lies on the A193 road 4 miles (6 km) south of Blyth and 4 miles north of Tynemouth.

The population of this ward at the 2011 Census was 4,923. Hartley is sometimes called Old Hartley to distinguish it from New Hartley. The place-name 'Hartley' is first attested in the Pipe Rolls for 1167, where it appears as Hertelawa. The name means 'stag hill'.

The station was to have been the terminus of the never opened Collywell Bay Branch Line, which, intending to promote Seaton Sluice as a resort, chose a more appealing name for their line and station.
