I plan on applying for a job with Amtrak as an engineer in a couple years (after I get a bachelor's degree) and am beginning to teach myself the NORAC rules (10th edition). I am currently teaching myself about signaling and reinforcing what I am learning with scenarios in Train Simulator 2013 (the new train sim that came out last week).
However, there are things that are really confusing me. Refer to the NORAC Rules PDF file located at http://www.blet57.org/NORAC.pdf.
Page 78 is rule 279 "Cab Signal Aspects".
1. In the SDU Display column, what is meant by "A green band"? For instance, the SDU description for cab speed is "A green band 0 to 60 or 80 mph". I know that cab speed is 80mph. It is 60mph if the SDU display doesn't show the signal speed OR if the cab signals aren't working. I need some clarification on this.
2. For the restricting signal and stop signal, how do I know whether to go 20mph or completely stop? I am at a loss to understand.\
Page 79 is the conformity between cab signals and fixed signals.
1. What does any of this mean? If the fixed signal indicates cab speed, my cab signal will be either "clear", "cab speed", "approach limited", or "approach medium"? How can it be more than one? I don't understand any of it.
2. What does it mean to just "approach"? What speed so I approach? I understand that approach medium is approaching the next signal at half of normal speed, but what the heck does approach mean?
If you can think of anything else that can help me understand signaling, I would gladly appreciate it.
Thanks!
