 Hydraulic machinery was provided from March 1858 by the Llanelly Dock Hydraulic Company, an entity evidently established for the purpose.With the South Wales Railway established, there was pressure to connect the dock at Llanelly to it by a broad gauge connection so as to bring business to the dock.The Dock was an intrinsic part of the Llanelly company's business, but once again it engaged in attempts to get the SWR to pay for the branch.
