CP Rail System Map - Trains Magazine

Being in former BN territory, often in casual conversation it's still referred to as "BN" at work.  Even by BNSF people.  There's a few instances where you can still hear "Q" being used. 

Old railroad names seem to last long after the original name, and sometimes the railroad itself, is long gone.  Nonrailroad related names for places also last so long that what or whom they were named for have been all but forgotten.
