Best laid plans... I assumed incorrectly that this train was headed out UP's Kansas Pacific main, so I positioned myself to catch the two WP GP40-2s - recently demoted from the Feather River mainline to less important duties in the heartland - passing between Salina's Union Station and a string of home-built, outside-braced MOW bunk cars. To my dismay, they headed out the infrequently-operated branch (to Lincoln?) instead. A quick sprint did allow me to catch the nose of 3545 as it passed a gap in the bunk cars. Close, but no cigar.
