Vital-Sim Inc.
Vital Sim, Inc., is the source of one of the most unique and celebrated products in the world of railroad signaling. The Vital Signal Logic Simulator (VSLS), introduced in 1991, enables signal engineering programmers to test the software they develop for vital signal logic controllers before cutover day. The amazingly user-friendly and capable VSLS system has substantially improved the performance of application programs in daily use and has eliminated hundreds of reburns in the cutover process. Now, Automatic Test feature is available that allows the user to turn "Test" on and walk away. At the completion of the automatic test he will get a list of tests that did not complete. It will be his job to determine why those tests failed which task is greatly simplified by the "drill-down" feature of the VSLS. Thousands of standard signal cutover tests will have been completed, as well as some that border on the exotic. With the active participation of several signal engineers in the freight and transit railroad worlds it is possible that Automatic Test has become the repository of the best critical thinking in railroad signaling.
Another product that is earning widespread acceptance is the Data Display and Analysis Tool (DDAT). This program allows the user to input a data dump from virtually any recording device or recorder board in use on any railroad in North America and display the data in a highly interactive format. Dual graphs allow two different time magnifications for the same data. Up and down arrows allow the user to instantaneously jump from one event of a specific nature to another. Pre-established filters screen data for common railroad signal maintenance problems such as "pumping contact" and custom filters can be written for unique occurrences. These filters eliminate the need to scroll through page after page of data, looking for a particular event. Up to ten different data files can be displayed in stacked "windows" and the time stamp can be adjusted so that all three screens show the same event occurring at the same time.
S&C Distribution Company is proud to be the US distributor of these widely respected, high productivity resultant tools.
