The SamTrak excursion train has ceased operating as of a few years ago. Two pieces of equipment, a GE 25-ton switcher and a flatcar, have been donated to the Oregon Electric Railway Historical Society museum in Brooks, Oregon. The 45-ton switcher and the logging caboose remain in Milwaukie, not in use.
The railroad is paralleled by a paved bike/walking trail from OMSI to Oaks Park, along the shores of the Willamette River.
Occassionally, excursions have been offered on the former SamTrak route using either the Southern Pacific #4449 and the Spokane, Portland & Seattle #700 (both mainline 4-8-4 steam locomotives); check with their respective groups, the Northwest Rail Museum, or the Pacific Northwest Chapter NRHS, for more information.
