Panama Canal

The Canal just reached a hundred years old, consisting of 3 locks with 6 steps to bring ships across Panama, from Pacific to Atlantic Ocean, or vice versa.

The locks are gigantic, very expensive to build and very difficult to fix, no mistake is allowed in driving the ship into the locks. So instead of the captain driving the ship into the lock, it is connected to 6 to 8 powerful tractors along the 2 side walls of the lock, to slowly pull the ship into position.
