421 class
From Wikipedia, the free encyclopedia
The 421 class was built in between 1965 and 1966 by the Clyde Engineering in Granville NSW. These mainline locomotives were a follow on from the 42 class units, which had one cab only. The locomotives retained the classic "bulldog nose" as with the other Clyde built locomotives, ie; GM, S & 42 classes.
The locomotices had a EMD 16-567C engine producing 1455kW/1950HP, with a EMD D32F generator and EMD D67 traction motors. The 421 class can achieve a top speed of 115km/h. They ride on Co-Co bogies and operate on standard gauge. They are 18.91m long and weigh 110 tonnes.
Five locomotives were bought by Northern Rivers Railroad which was then sold to Queensland Rail. QR in the early days of operations in NSW traded under the guise of Interail. Other units saved were 42101 which is preserved at the Goulburn Roundhouse Heritage Centre (private), while 42102 is preserved at the Dorrigo Steam and Railway Museum.
