Vintage Carriers – 1967: A Trainload Of Buicks And A Truckload Of Pontiacs?

I’m pretty sure that I’m seeing a trainload of Buicks in this image, though I’m not so sure if those are all Pontiacs on the Chevrolet truck. A truckload of Pontiacs, or something else? Hard to tell from this angle. But does it really matter? I could take any of these home and be rather content.
