Train Symbol "Line Segment" Codes?

[TheVARailFan]

Hi, I know that trains identify themselves on the road by just the train number, but I'm curious as to the true train ID, which includes the terminal info. i.e. NS 23G out of Norfolk on the 12th of the month would be listed as 23GV312, only the "V3" would be what the line segment for Norfolk actually is. Does anybody happen to know what the codes for the former VA Div. and current Pocahontas Div. are?

Thanks & Best Regards,
