[1] The Corris Railway maintained their own Machynlleth station adjacent to the mainline one, with connecting passengers services until 1931 and slate transfer facilities until 1948.

[2] The lower yard of the station contained a number of sidings that served transshipment wharves connected to the Corris Railway.

This was later expanded by Cambrian Railways, but the extensions were demolished after 1966, when the depot ceased to be used for servicing steam locomotives.

[8] Machynlleth is the location where the majority of eastbound or 'up' trains from Pwllheli and Aberystwyth combine to go forward as one towards Shrewsbury and Birmingham International.

In the 2015-16 timetable, some additional Shrewsbury - Aberystwyth services operate to give an hourly interval frequency during the morning and evening peak periods.

[10] In 2011, The Bluebell Railway discovered a well-worn totem sign from Machynlleth during the excavating of Imberhorne Cutting as part of the northern extension to East Grinstead, which was used as a landfill site by the local council in the late 1960s.

Train running information is provided by customer help points, CIS displays, automated announcements and timetable posters.
