Those 7300s were ex-CN and GTW units (snow shields behind the cab, plated-over class lights above numberboards) and were straight SD40s, so those Flexicoil trucks would be correct, but in silver, they may be borrowed from an ATSF unit! 7305 was CN 5036; built Feb 68, rebuilt Sep 99, retired Jul 04. Rebuilt from SD40 to SD40-2. Data from http://archive.trainpix.com/bnsf/EMDORIG/SD40-2/INDEX.HTM
