The 1620 class was a class of diesel locomotives built by English Electric, Rocklea for Queensland Railways between 1967 and 1969.

The 1620 class locomotives are similar to the New Zealand Railways DI class, also built at the Rocklea works.

History

[edit]

The 1620 class was an evolution of the 1600 class being fitted with a hood nose. They operated in Central and North Queensland as well as hauling commuter trains in Brisbane.[1][2][3] The class was withdrawn in the mid 1990s with some sold to John Holland and exported to Malaysia and The Philippines.[4][5]

1647 has been recently noted to still be in use with Lafarge cement at Padang Jawa, near Kuala Lumpur, Malaysia

Six have been preserved:[2]
