4. Introduction to CATS Prototype examples Setting up CATS as a better magnet board Signal aspect and indication determination Setting up CATS as a dispatcher panel for a model railroad Advanced CATS Outline Computer Automated Traffic System (CATS)

5. CATS is a computer program for controlling the signals on a model railroad (ABS, APB, CTC) CATS is a dispatchers panel for a model railroad CATS is a model of a dispatchers panel CATS is a suite of programs to assist in operating a model railroad in a prototypical manner Introduction – What is CATS? Computer Automated Traffic System (CATS)

6. CATS is computer system independent CATS is not tied to a particular control system CATS is a JMRI application CATS is not PanelPro CATS is freeware and open source CATS is a modern looking dispatcher panel inspired by Digicon Introduction – What is CATS? Computer Automated Traffic System (CATS)

7. The primary CATS user is the model railroader who wants a kit for signaling –Simple to set up –Simple to use –Realistic The secondary CATS user is the purist –CATS cannot be everything to everyone –CATS follows the good enough principle Introduction – What is CATS?

Stop Stop before any part of train or engine passes the signal then proceed at restricted speed, not exceeding 15 MPH prepared to stop at any obstruction, through the entire block. Flashing Stop and Proceed Proceed on diverging route prepared to stop before any part of train or engine passes the next signal. Speed through turnout must not exceed 15 MPH. Speed to next signal must not exceed 30 MPH. Diverging Approach Slow Proceed on diverging route. Speed through turnout must not exceed 15 MPH. Diverging Clear Slow Proceed on diverging route at prescribed speed through turnout prepared to stop before any part of train or engine passes the next signal. Trains exceeding 30 MPH must immediately reduce to that speed. Diverging Approach Proceed on diverging route at prescribed speed through turnout. Diverging Clear Proceed.

39. Speed Signals – the signal indication tells the speed limit on the block being protected and one or more subsequent blocks Route Signals – the signal indication tells what route thru an interlocking plant (security element, OS section) will be taken Speed versus Route Signals Computer Automated Traffic System (CATS)
