Built in 1938, the SP&S 700 is the only surviving specimen of the E-1 class 4-8-4 Northern type steam locomotive. It’s the third largest operating locomotive in North America. The driving wheels are 6 foot 5 inches tall.
The SP&S 700 and two other locomotives reside at the SE Portland Brooklyn Roundhouse. But they are being evicted! The Oregon Rail Heritage Foundation is working to secure a new home for these historic behemoths near OMSI.
Two years ago Heather and I had an opportunity to check out the SP&S 700 in person. Our friend Brent worked for Burlington Northern Santa Fe at the time and he invited us to a holiday visit by the locomotive to the Vancouver, Washington rail yard.
