Underground tunnel for player

[js1]

So we have underground belts and underground pipes, but what about the poor player character? Maybe there could be a similar "underground tunnel", which would let player enter on one side and appear on the other side (after some time, depending on movement speed). So for instance one could make the connection between different walled areas, or just make it easier to move around complicated factory.
