CONTINUOUS MEASUREMENT AND CONTROL OF THE SPEED OF WAGONS SHUNTED OVER HUMPS. COSTS OF THE VARIOUS SYSTEMS

The report contains a calculation of the costs of automatic hump yards, incurred for the following systems: (a) DB system with primary and secondary retarders and conveyor devices; (b) SNCF system with primary and secondary retarders; (c) BR system with hydraulic retarding and boosting units. The cost calculation according to uniform standards is based on the installations described in Report D 74/RP 4 with 32 and 48 sorting sidings and it covers: (a) The cost of investments, (b) Capital charges, (c) Operating cost. For each installation the total costs and the specific total costs relative to one shunted wagon are indicated. A comparative assessment of the various systems according to the cost involved is rather problematic on account of the divergent economic conditions. The indicated details can only be used as informatory for special investigations.
