The final Johnsonville Branch services to be operated by the DM/D class ran on 19 March 2012. The train, consisting of DM 27 and DM 556 and driven by Phil Gibbs, crossed FP/FT 4155 and another Matangi set at Ngaio where impromptu speeches were held to farewell the trains, which subsequently arrived back at Wellington late. This also happened to be the last time both DM 27 and DM 556 "Phoenix" ran in service, both being withdrawn following the final run. Due to issues surrounding noise using Matangi units on the Johnsonville line, three test trains were run with two two-car DM/D sets; the last of these being run on 15 June 2012 using sets DM 441 and DM 510.
