(Case No. 8415) A variable load brake control equipment for a road/rail type vehicle comprising variable load brake apparatus located between the auxiliary reservoir and a supplemental volume reservoir in the supply line upstream of the vehicle control valve device. During braking, the auxiliary reservoir pressure and the supplemental value reservoir pressure combine to provide an unmodulated buildup of brake pressure until the brake pressure reaches a value that varies as a function of the vehicle load. At this point, the variable load valve device operates to isolate the auxiiary reservoir, so that a continued buildup of brake pressure is modulated by reason of the fact that the supplemental volume reservoir alone supplies braking pressure.
