The 2250 class are a class of diesel locomotives rebuilt by Queensland Rail's Redbank Railway Workshops in 2004.
[1][2][3] The rebuilds included new cabs, Dash 2 electronics, ZTR traction control equipment, EMD 645E engines from 1502s and the replacement of the roots blower supercharger with a turbocharger.
[2] They were also ballasted to 110 tonnes (110 long tons; 120 short tons) as they only operate on heavy coal trains.
[citation needed] 20 locomotives were sold to Transnet in South Africa in 2014.
[4] In July 2019, 5 were brought back into Australia for use on the iron ore railway to Whyalla steelworks.
