The 1700 class was a class of diesel locomotives built by Clyde Engineering, Eagle Farm for Queensland Railways in 1963.
Initially the 1700 class operated branch line services out of Roma before being relegated to shunting duties. Later they were modified for driver only operation receiving a larger windscreen. They were withdrawn in 2000. 1706 was written-off in the 1987 Bindango Derailment. 1707 (without bogies) is privately owned and stored at the Queensland Pioneer Steam Railway. The cab of 1710 is at the Workshops Rail Museum, converted to a driving simulator.
As of September 2025, 1707D is now back on bogies and transferred to storage (possible restoration) at the Zig Zag Railway, Clarence NSW. This means that there are now no complete Class 1700 locomotives in Queensland.
