NR class

The most frequent visitor along the main Adelaide Melbourne line is the NR class. The 120 locomotives were ordered in 1995, from A Goninan & Co, for the National Rail Corporation. The order was split in two, with half being built at Broadmeadow; with the others at Bessendean. All were taken over by Pacific National in 2002.

While out and about, came across the 4PM6, with one of a few, yet to be repainted Grey and Marigold NR class leading, in NR 72.
With the NR class now going through a re-power programme,where the GE 7FDL-16 prime mover is being replaced. With NR 23 the first locomotive through, the only visible change is LED replacements in the head and marker lights, plus inline refueling equipment.
Looking back, National Rail published the following livery diagrams on their website many years ago.
