[4] The Narberth Road and Maenclochog Railway (NR&MR) opened in 1876, the junction of that line being to the west of Clynderwen station; and the NR&MR trains to Rosebush used a bay at the eastern end of the up side of the station.

[5] Initially trains had to reverse in and out of the platform, but with the extension of the Rosebush line to Letterston by the North Pembrokeshire and Fishguard Railway (NP&FR) in 1895 (the NP&FR having taken over the NR&MR), the layout at Clynderwen was improved.

[7] InterCity 125 services ran through Clunderwen to Milford Haven until the early 1990s, terminating in 1994.

[8] Trains that stop here go to Milford Haven westbound and to Swansea, Cardiff Central, Crewe and Manchester Piccadilly eastbound.

[9] A basic two-hourly frequency runs Mon-Sat, with fewer trains on Sundays.
