[2] Features typical of a small rural railway station were present at Mangamahoe from its early years as official records mention a wooden-fronted passenger platform (1903), goods shed and station building (1905), wooden-fronted loading bank (1924), staff telephone (1929), and Ways and Works Branch shed (1962).

A tablet porter's room was located in the station building and water closets were provided for the convenience of staff and passengers.

The Inspector of the Permanent Way advised in June 1959 that trap points had been installed at Mangamahoe and the loop roads closed off.

[4] This service had been running between Napier and Palmerston North since the line through the Manawatū Gorge had been completed several years earlier.

The Wairarapa Mail passenger trains continued to run but in 1944 were reduced from their Monday – Saturday timetable to a thrice weekly service due to a severe coal shortage.

[6] Several years later the Rimutaka Tunnel was opened, bringing an end to the mixed trains[7] that had been plying the Wairarapa Line and the withdrawal of the Wairarapa-type railcars.
