This line is divided into a number of portions.
This junction opened in 1879 when the Newport Railway was opened to meet the 1878 Tay Bridge and Associated Lines (North British Railway) at the south end of the Tay Bridge [1st]. The southern end of the bridge was modified with the addition of a new girder bridge which met the existing bridge offshore. The junction was entirely offshore.
This was a single platform station on the north side of the line. The station building was at the west end. The building was brick built, rectangular with a flat roof. There was no goods yard.
This was a two platform station with a loop on a single line. The main station building was on the eastbound platform, at its south end. The signal box was half way along the same platform.
