How does a train change lanes? And yes, it is more complicated than it seems because between the rigid rail and the train without a flywheel, it poses some questions:
How does the train run?
What is the role of the driver in the direction of the train?
Why is there a steering wheel if it doesn't turn the wheels?
What is a referral?
How does a referral work?
...
And lots of questions around all that :)
