It's not exactly correct. If I were building this model NOW, I would use the Kadee pre-1950 PS-1."
Ken, I agree with Tim. While the Evergreen Roundhouse line has some of the nicest UP factory lettering ever offered, I'd wait until the pre-1950 Kadee PS-1 comes out unless you have an absolute life-or-death immediate need for a Class B-50-40. The PS-1 is such a ubiquitous prototype that there's surely another off-line car that fits your needs that is closer to the Intermountain model.
