The 2250 class are a class of diesel locomotives rebuilt by Queensland Rail's Redbank Railway Workshops in 2004.

History[edit]

The 2250 class are former 1550 class (6), 2130 class (all 11), and 2141 class (all 8) locomotives that were rebuilt 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.

20 locomotives were sold to Transnet in South Africa in 2014.[4]

5 were brought back into Australia by GWA for use on the Whyalla network, releasing GWN class locomotives for service in Queensland.
