So I don't know whether to post this here or not, but what the heck - better late than never.
A couple months ago, probably back in June, I was down in the CEID biking down the bikeway that goes to sellwood, and I noticed they had recently - within a few months - rebuilt the heavy rail line that connects to the train yard in the area to the (I thought) abandoned rail line that goes south and parallels the bikeway. There were also about 10-12 little rail inspection cars that zipped by with flashing lights carrying official-looking people in suits. They looked like they were from the city, but not sure.
Anybody know what this is all about?
