Now that’s something you don’t see everyday
The remains of Portland Traction are not a very busy freight route, and the trains run on demand, so it's a very rare occasion when a train comes by when I'm going across the bridge (I've seen the working eng (SW-1 #100) pulling a short freight, and I've seen the new working eng (SW-9 #902) running light down to the SPYellow Menace interchange, but that's it for 10 years of living in SE Portland.) But even given that, seeing the third largest active steam locomotive in the United States come rolling down the line pushing a passenger car, three cabeese, and the SamTrak open-air observation car would count as fairly unusual.
