They sure have joined forces, if you believe this hopper. At least half a dozen in the yard, most likely ex-EEC's or GCCX's, CP has had many ex-CNW PS-2's go through wearing those reporting marks, most still wearing CNW's logo and paint.
This way when UP takes over, they'll get their old junk back. LOL. Good thing CP got rid of their SD40-2's in the 5400 series already!
