Longitudinal behavior of a train, both as a whole and by individual vehicles, is analyzed, with drawbar forces predicted. Shock absorbing linkage systems, such as draft gears, hydraulic cushioning units and sliding sills may be modelled in individual subroutines for "plugging into" the program. The program is general enough to simulate train behavior over arbitrarily chosen track to the extent that any combination of profile and curvature may be used. Motive power, number, characteristic behavior and schedule of application are also arbitrary as are brakes: electrodynamic with characteristic behaviors or penumatic independent and automatic with assorted brake valve types and arbitrary brake application schedule. Each shock absorbing or linkage unit may be modelled individually. This program could be used as a design tool for linkage and shock absorbing units as well as for consisting, powering, braking and all other represented elements (too numerous to mention) affecting longitudinal behavior.
