Oh, I'll leave the wiki work to some young buck with time on their hands. A1 is right about the non-hyphenated UP symbols. I must have been in a BNSF frame of mind; and even there, hyphenation or single spacing after the train type character seems to vary depending on the official and unofficial sources one references.
Something else worth mentioning. While UP chose to recognize the Edmonton origin of the CP trains which became EDHK symbols upon reaching the border, they chose to ignore the Calgary origin of the CP trains which became ETHK symbols upon reaching the border. I don't want my previous post to give some folks the impression that Canadian carloads simply materialized out of thin air at Eastport to spawn those ETHKs.
A book that's well worth the price for understanding UP's former SI route can be ordered here:
