Indeed -- it is like if arguments were things to transport, and analogies were cars... wait, no, they are railroad cars.

So the argument is a heist occurring on a train, so we've got the thing that we're trying to heist (which would be our point) and then we're shifting it from one car to another. And some of the analogies here are clearly like passenger coaches, but others are more like those... coal transporting car, whatever they are called... and at some point we move to the inappropriate railroad car and drop the point in the coal which obscures it.

Anyway, the point is that at some point you really just hope that some conventional train robbers will show up and derail the whole thing because it has gotten too convoluted to follow.
