The Class 47 (and Class 45 too) train brake does not behave correctly at all. When you click initial setting it goes sometimes to 21psi, sometimes 33, and sometimes 40. It is all over the place. Then after you apply initial, and progress it a bit further the needle ends up way off the gauge. The Class 47 in the West Somerset Railway seems to behave correctly, but not the North Transpennines version. This needs to be thoroughly investigated and tested properly because I am not the only one who has noticed this disaster!! Does anyone else find this ?
