the container is unloaded and is brought to the yard block on the truck once it reaches the side of the RTG (I put more uptime on the rtg so it creates a queue)
but visually the other trucks occupy the same space as the 1st unit that arrives.
what type of node connection (non-passing/non connection) should be used so that the others wait to be served and see the waiting queue
model on cloud: truck queue.fsm
