Abstract:

The profile simulation program was written to help in designing a hump yard. Optimum hump yard grades and retarder placements can be extracted from the outputs of this simulation program. The movement of railroad cars over different hump yard profiles can be simulated, so that the consequences of different hump yard designs can be discovered before implementation. The CAPACY model was designed to emulate manual capacity calculations for railroad classification yards. The output from this simulation model can help in planning railroad classification yards. By running this program with different traffic level inputs and analyzing the simulation output, one can estimate the type and size of classification yard needed...Software Description: The program is written in Fortran programming language for implentation on a DEC System-10 computer using the TOPS-10 operating system.
