The 2250 class are a class of diesel locomotives rebuilt by Queensland Rail's Redbank Railway Workshops in 2004.
The 2250 class are former 1550 class (6), 2130 class (all 11), and 2141 class (all 8) locomotives that were rebuilt in 2004.
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. 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.
