China Railways is all set to press the first HXn3 diesel locos into service after successful completion of the cold weather trials at temperatures down to -40°C.

The 120kmph HXn3 Harmony class, also known as JT56Ace is powered by EMD’s 16V-265H engine, rated at 6000 hp and meets US EPA Tier 2 emissions regulations.

The AC traction drives it and micro-processor controls help it maximise performance and fuel efficiency.

The 4400KW twin-cabbed loco has a full-width monocoque bodyshell with an internal passageway between the two cabs for safety in severe weather conditions.

To meet the severe cold conditions, the air dryers for the brakes have inbuilt heaters, and an air system for engine start-up.

Each loco will have six 8.1KW cab heaters, thermal insulation and heated windscreens.
