 The line at Swansea was to divide there, the passenger terminal being at a low level, and a high level line was to continue to the docks, crossing the River Tawe.Construction of the line was considered to offer no great difficulty, but the Board of Trade inspector's report of May 1865 required considerable improvements before opening.The company dragged its feet over complying with even trifling improvements required, and moreover started running passenger excursion trains on 29 May 1865 (to an Eisteddfod), and a regular passenger service from 1 June 1865.
