The mineral operation on the Barry Railway was of course focused on the sidings at Barry and Cadoxton, where considerable sorting activities took place and dock storage was necessary waiting for specific ships to become available for loading. About 100 miles of sidings were at the location, and access to the sidings by arriving trains resulted in serious congestion. In 1898-1899 a burrowing junction was constructed at Cadoxton from the sidings and goods lines on the north side of the line to No. 1 dock.
