Yes Bill, that's how every RGS and D&RGW double deck loading chute I've ever seen was built, whether in pictures, drawings, or real life. The fact that there were no sheep being loaded on the lower deck of the original picture in this thread and no ramp up to the lower deck is what got my interest. Jimmy Blouch suggested that the Silverton chute was different and loaded one deck at a time by raising and lowering the ramp. That sounded plausible until I thought about it for a while. My current thinking is that they had loaded all but a few sheep and they just happened to put the last of them in the upper deck. In the picture in question, it looks to me like the upper chute is closest to the camera and the lower chute is on the side away from the camera.

I have been around loading chutes that allowed the ramp to be raised and lowered, normally to match the bed of the truck in which livestock was being transported, but those ramps are very heavy to support cattle and I wouldn't want to be raising and lowering them between decks of a string of stock cars. Besides, I didn't see certain features that those ramps have.

While on the subject, something else I haven't seen is how the gap between the ramp and the car is bridged. I assume there is a separate piece that was inserted, but I've never seen it. I would assume this section of the ramp is stored somewhere handy. I am not talking about the fold down piece that crosses over the lower ramp. I'm talking about something that would go between the fold down piece and the car. I doubt the sheep could levitate.
