Several years ago BNSF painted an out of service SDP40F in a special Maersk-Sealand paint scheme. It was taken to several special events and then eventually donated to the Pacific Northwest Railroad museum in Portland, OR. It has been made operational again and has seen some service on the Portland & Western RR. Now lettered "DLMX 644", I believe it is the only SDP40 remaining.
