RAILSIM Safe Braking Distance Calculator

Safe Braking Calculator

RAILSIM Safe Braking Distance Calculator supports calculations for multiple-stage runs.
Each stage is user-defined, including its duration and type of tractive and braking effort curves used.

RAILSIM's Safe Braking Distance Calculator calculates safe braking distances for "worst case" signal design purposes. Like the Headway Calculator, the Safe Braking Distance Calculator can be used from either RAILSIM Editor or from RAILSIM TPC. It can analyze any number of defined train types from any number of Signal/IJ/Bond Locations, using these powerful features:

Both Forward and Reverse safe braking distance processing;
Processing of single or multiple stages in a single run (Free Running for 3 seconds, followed by Coast for 8 seconds, followed by Braking to a Stop, for example);
User-specified train compositions, including testing of multiple train lengths;
User-specified settings and parameters, including Rear Wheel to Coupler Overhang distance, ATC Receiver/Trip Cock Setback, and a buffer distance (typically the positional accuracy uncertainty);
Processing of multiple velocities for a single location,
Adjustment factors for reducing curves and for all braking curves.

When accessed from RAILSIM Editor, this add-on lets you generate an engineering drawing in CAD DXF file format in addition to the traditional RAILSIM Safe Braking Distance Report.
