By Golly he did. I was just out on a drive, on Sunday, to follow the BNSF Bayard Line and run up along the CN/IC north of Denison IA. I found the CN at Denison and started to chase it west when UP Dispatcher 19 asked a stack train to ease up a bit as Amtrak was coming thru Dunlap. I headed west where I met the Amtrak Detour. Made a U-Turn and gave chase. Took a couple of pacing pics and then just in the nick of time another westbound stacker cleared the view for a threesome with UP AMTK and the CN westbound. And I still made it to Wall Lake in time to see an eastbound CN Train. More on that after midnight when I get home from work.
