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.
