Railway Terrace ran parallel with the railway branch line that once ran from Newsham to Blyth. Now a walkway where line once lay.
Railway Terrace was on the east side of the line. The pit yard and miners houses of Cowpen Colliery lay on the west side of the line. ( now Blyth Sports Centre and small estate )
Drinkers in that area would have frequented the Cowpen Colliery Inn ( now called The Top House, which was once it's nickname) , on Harper St, and/or the Thoroton Hotel ( now I think called the Burglar's Dog) on junction of Harper St/ Renwick Rd.
But this area was never called or regarded as Newsham- firstly Waterloo then Blyth.
Old maps showing Railway Terrace can be seen in Blyth section of web site
communities.northumberland.gov.uk ( choose the 25" version maps)
Also plenty of Blyth photos on this site- but not of this end of Blyth.
