ABSTRACT:
A microprocessor based brake pipe pressure control system for one or more cars of a railroad train wherein the local exhaust of each car brake pipe pressure, under control of an electro-pneumatic valve, is individually regulated such that the gradient of the resultant train brake pipe pressure closely approximates the natural brake pipe pressure gradient for any given brake pipe pressure reduction.
