If they did, something like this could be a tad dangerous.
Here is my unfinished level when I decided to run it and, based upon where the hanging pendelum end is when the train runs off, the train cab can bounce into the valley, somehow get airborne and launch across the body of water, and then bounce off the other side of the cliff and end up going off the level, still airborne. Other times I have seen it crash completely when it falls. Yet others, I have found it launch airborne OVER the cliff, touch down, and bounce off the map in the forward direction...
