Hello everyone. I have a question regarding CSX train symbols. I apologize if this question has been asked before as I am fairly new to this site. When a train's three number symbol is followed by another two digit number, what does this mean? An example of this would be Q416-23. I photograph the River Line mostly and usually the symbols are of the three digit variety (e.g. Q111) but occasionally I will hear the extra number added and was curious as to what this was. Thanks in advance for any answers.
