What is the LSD in the BLC wagon?
So as to obtain this a changeover mechanism called "Load Sensing Device" (LSD) is interposed between the bogie bolster and spring plank. The mechanism gets actuated at a pre-determined change over weight and the distributor valve which has the additional feature (Le. EK PT/C32) controls the brake cylinder pressure

BLC wagons are provided with automatic two stage empty load device to cater for higher brake power in loaded condition instead of the conventional manual empty load' device. With the provision of this, brake cylinder pressure of 2.2 kglcm² is obtained in empty condition and 3.8 kglem2 is obtained in loaded condition.
