At the Dalles Dam there was a tourist train that tok visitors on a tour of the dam. It's been years since going there so I'm not sure if the train is still there. It was a fun ride.
I live in The Dalles and I grew up with this train. I have a memorial site on facebook you can search for it by @thedallesdamtourtrain or thedallesdamtourtrain.weebly.com I am still working on the site and facebook page.
I still have the websites the weebly one listed above and i have a Facebook page if anyone has more photos or video of the tour i am looking. I am also looking for earlier photos when the train was green and yellow.
