The DXR locomotive is one of the Largest and most powerful CoCo diesel locos of the Tranz Rail fleet. The 7.25" gauge loco will end up 3 metres long.
The bogies are powered by two 24v 40a EMD motors which drive the centre axle via a worm drive reduction. One of the motors is clearly seen in this picture.
All wheels on the loco will be braked. These are operated by Vacuum. The vacuum cylinder is clearly seen on the right hand picture.
The main platform is taking shape, the bull bars have been fitted and the well where the fuel tank has been made to accommodate batteries.
The cab is taking shape. It is to the new universal cab design being adopted by Tranz Rail as they replace the cabs on their locos. Notice the detailing along the sides of the bogies. The 300mm ruler gives some idea of the size. Just behind the cab is the vacuum pump. The vacuum storage cylinder is under the short bonnet.
At the other end of the loco the control panel is taking shape. It incorporates ammeters, volt meter, vacuum gauges, switches, speedometer and socket for remote control. The top has yet to be shaped to fit under the long bonnet.
The electronic controllers are situated behind the control panel. Isolating switches are provided for the batteries and both motors.
Side extensions were added to the fuel tank well to detail according to the new DXR universal fuel tank.
By August 2001 the body was taking shape. The defining lines of the rebuilt Cab was now visible.

The painting is almost complete. The colours are the present Tranz Rail livery.
On October 3rd 2001 the DRX made it's first test run on the track followed by hauling passengers for the following 5 hours.
Loco now back on bogies and ready for the final wiring and testing.
The 5" DH Shunter looks rather small beside the DXR.
Complimentary ride cars were completed soon after.
Long Bonnet and side doors soon appear and the bodywork is ready for painting.
