An alert fan of the website alerted me to an image on the LoC.gov website showing the steam switcher in action! These photos are so rare I just had to see. Wow! The photo is far away, shot from Rosslyn, looking toward Georgetown, but there it is. It’s making quite a good bit of smoke and appears to be idling or moving slowly. Can anyone identify the class of loco?

Here is a link to the site:

By the way, there are many, MANY fantastic images in and around this area to be found on the LoC site. Happy hunting!
