    More often than not, because the larger container won't fit in the well fo the car.

    Length restriction.

    The container on the bottom is probably a 48 foot type. That's about the max size you can fit in the well. The one on top is most likely a 53 foot type. So, it has to sit up there to be carried since it can't fit in the well.

    Edit:

    Looking at the pic, you see the number 48 on the lower container? That's its outside length. Roughly 48 feet. The 53 on the top box, is its length.

    smaller containers are made for heavier loads, so if you've got 2 loaded containers of different sizes, the heavier goes on the bottom, and the heavier container is most likely the smaller. Loading double-stacks is a very complicated subject.

    There are cars designed to carry 2 53' containers (I have some HO scale Thrall models made by Walthers). There are even newer cars designed to carry 4 (yeah, that's right, 4) 28' containers, so they've got 56' wells (2 on the bottom, 2 on top).

    I recently had a discussion with my brother-in-law on this. He works for CN Rail in Edmonton. His reply is that, unless special circumstances dictate otherwise, the railroad doesn't care whether the larger container is on top or bottom. Containers are loaded in a manner that is easiest for those loading. The CN Intermodal cars are also built slightly different than the one shown above.

    Brad, containers come in 4 common sizes, 40, 45, 48, and 53'. The older well cars can only fit at most 45 or 48' containers, so if you have a 45' on the bottom, than you can put a 45, 48, or 53' on top. Newer well cars are now 53' long, and I have begun to see 53' containers on the bottom, and in some cases, a smaller 48' container on top.

    How's the top loaded Container fixed on top of the one below so it won't fall off?

    Gravity. The container is heavy enough that it will stay down and its locked in.

    To add to Rob's reply, there are a set of locking sockets on the undersides of the containers that mate with pins on the roofs of the containers.

    There is a thingy called twistlock. It is kinda like a plug that fits in holes in the bottom of the container. After having settled in, these locks turn and the containers are fixed to each other.

    And to add fuel to the fire.

    The containers are always set up pre-blocked. Therefor, containers no matter whether they are 20' 40' 45' 48' 53' are going to the same intermodal terminal.

    So where you see a single well car (not drawbar connected) the containers are both bound for the same place. On a well car that is either drawbarred or articluated, sometimes you see the car underutilized. Reason being, the containers are destined for the same place. Cant have a car loaded to the gills with half the cars destined for Seattle and L.A. It is just not possible.
