Somehow I missed the fact that this was already well under construction. It will be a really nice addition to that area around OMSI and the new bridge and rail lines.

Photos: Construction of Oregon rail museum
General contractor Lorentz Bruun began work on the Hennebery Eddy-designed Oregon Rail Heritage Center in November and expect to be finished in July. The 19,200-square-foot project, being built near the Oregon Museum of Science and Industry in Southeast Portland, will house three historic locomotives and one car. In addition to space for working on the equipment, the building will contain offices, a conference room, and a public viewing and interpretive area.
