GAS TURBINE LOCOMOTIVE TESTS

This article described dynamometer car trials on Western Region of the British Railways to check fuel consumption and thermal efficiency. Also checked was the designed tractive effort-speed characteristics, the most notable feature of which is the restriction of the starting tractive effort to 31,500 lb. and its maintenance up to a speed of 21 mph. Curves presented in Fig. 1 show that speed could not be checked properly on the dynamometer car runs. Another feature brought out by Fig. 1 is that thermal efficiency of gas-turbine locomotives rises with increase of load, though of course on the drawbar value it falls with increasing speed on any given controller notch. The curves shown in Fig. 1 and 2 refer to drawbar outputs and consumptions.
