Placing down cargo wagons or train engines occasionally seems to ignore the hitboxes and cause them to overlap, as shown in this screenshot when I placed 4 wagons.
This seems to only happen when when I am standing on the track, which keeps the wagon/engine from snapping, but still allows me to place it well inside the engine's hitbox:

Re: [0.15] [kovarex] Cargo Wagons and Train Engines Overlapping
Well, in this specific case. The collision boxes don't actually overlap, tre train can't be moved to be connected to the train when the character is in the way, so it is built this way. The collision boxes are smaller to avoid some strange collisions in tight curves, so this kind of tight placement is possible (try to run the train next to each other).
