SP 4449 Big Steam Train Incredible Sound Effect!
https://prrt1steamlocomotivetrust.org/ - Please help fund the T-1 Trust! They are a wonderful organization, building an advanced new 4-4-4-4 T-1 steam locomotive from scratch!
The Southern Pacific 4449 taking off from a dead stop at Oaks Park, OR, pulling the ORHF holiday express. Lots of throttle, and just listen to that sound!
