 The pit at Lingerwood eventually became Lady Victoria Colliery and Newbattle Colliery, later with a considerable internal branch line between them and the main line.The pit at Arniston Engine was served by a tramway branch from Arniston, on the main line, which is located just short of Gorebridge station.In compensation for the expense, the Marquis was allowed to use the North Esk viaduct on the E&DR for his coal free of charge.
