Hard to believe but I think some eastern railroad(s) use a yellow to indicated "Proceed at restricted speed" and in Chicago an Amtrak train rear ended a freight after passing a yellow signal according to reports. I think I've seen the rule that supports this indication but can't remember. Not a great idea to have such a variance in rules in one country's railroads. If you've seen a yellow all your life as a signal that indicates the block is clear to the next signal and then end up running on another railroad this can be trouble. I remember right after BN replaced yellow/red flags with yellows an engineer blew by a red flag. At 3 a.m. none us is at our best to interpret serious rules changes on the spot. Of course BN went back to the yellow/red years later but we were all joyful of the never ending rules changes we work under.
