SVRy has 6 EBT hoppers. As I recall 2 or 3 have SVRy trucks which are virtually identical vulcan trucks, but with the SVRy cast in the side frame instead of EBT RR & coal. This is because some of SVRy's late built heavy duty wooden flat cars went to the WP&Y in the late 40's and somehow by intention or accident several set of trucks ended up under EBT hoppers that were at the WP&Y which is where SVRy in the modern day got their hoppers. Pretty amazing that they went from Penn. to Ak. and then down to Ore. SVRy actually got 7 hoppers, but one was cannibalized for parts for the other 6.
