The few proto photos that I’ve seen of SP MT-4s showed them in passenger service. I have four questions regarding these machines: 1. Did they ever seen freight service as well? 2. Were any of them still running when SP ran out their first Geeps and SDs? 3. If they ran concurrently, would all of those last Mountains had the Skyline fairings? 4. Did any MT-4s ever make it to Oregon?
