The crew on M337 has run out of time and now sits and waits for a relief crew at the Galena Depot. The inbound crew went to work at Hawthorne Yard in Chicago, IL, overnight and with heavy delays didn't make it the 174 miles out to Dubuque, IA. The outbound crew coming for the train will make the final leg of the trip to Waterloo. Today's M337 is running old school power with a leaser CEFX SD40 that came off the BNSF, and a BNSF GEVO.
