The sleeper's upstairs toilet on the I model is oriented differently than any others. In that one toilet the "throne" faces the end of the car instead of the hallway door. That configuration creates an extra square foot of floor space that makes it much easier to use. Plus it allows a window (with a curtain in case you're not out in the country). They should all be that way.

Speaking of toilets, the Superliner I had a button to flush and the II flushes when you put the lid down.

As for the bedrooms, I prefer the hanger rod over the closet. Though the closet looks nicer, but it is easy to forget you have stuff in there when you get off. On the hanger it is in plain sight. We hung a garment bag with zipper pockets on the hanger and you can easily access the pockets while it hangs.

The upper bunks are definitely too cramped on all Superliners. It would really help if they had even a small window at the head of the bunk to relieve the claustrophobic feeling you get up there.

The low ceiling also makes it hard to get into. We had four of us traveling last summer, my wife and I plus my mother and sister. Neither my mother or sister are very agile and they were not able to get up there without great difficulty. My wife and I ended up in the two top bunks.

But even with these challenges, I really like the Superliner cars in general. They feel like a mini hotel on wheels. And the kid in me thinks the double-deck configuration is just plain fun.

1) Superliner I's have european stye trucks while the II's have GSI trucks. Most II's I've seen have silver trucks, while the I's have black.

2) Every Superliner is in the phase 4 scheme. So you think it would be hard to tell the difference between I's and II's. It's actually quite easy. The I's were not completely repainted. A decal was simply put over the existing wide phase 3 stripes. As a result the silver of the car doesn't match the silver on the decal. The II's were painted in the phase 4 scheme so the silver matches thoughout the car. To tell if it's a I or II, just look at the red, white, and blue.

3) Superliner II sleepers are named after states. So if it says sleeping car by the entrance door, it's a Superliner I. If it is named after a state it's a Superliner II. The auto train has it's own sleepers named after Florida beach cities. All of these are Superliner II's. I have seen one named Superliner I sleeper. It's named after George M. Pullman, the I's were built by Pullman.

On the westbound trip we were in a Superliner II named Oregon. It was nice and clean and showed no signs of wear and tear. However, the A/C on that one worked too well. I had to wear a sweater through the desert!
