With four big EMDs for power, an FWWR Cresson Turn, symboled FWCR, crosses the road into Ash Grove Cement just south of Tower 60. The lead SD40, FWWR 2023, started life as SP 8455.
The EMD SD (special duty) series are a strong and reliable kind of locomotive which still serve America's rails today. They have proved themselves reliable by clocking in several million miles of freight service over several decades.
