The 421 class were essentially a follow-on from the 42 class, with the main difference being that the 421 class included a second cab, at the rear of the loco. Like the 42 class, most of their work was on mainline passenger and freight services. Half of the class have been sold to the Northern Rivers Railroad. 42106 was to be fitted with a gas turbine at one stage; however this did not go ahead.
 
Northern Rivers Railroad:
These locos were used for most of NRR's operations. They were sold to QR Interail to become their 421 class.
