Preliminaries
•	Get a key to the model railway room!
 
Tasks
T3A1: Round and Round!
Use SCCharts (and KIELER) to model a railway controller for the model railway!
•	Choose any train standing in the Inner Circle Station and let it travel around the circle at a speed of 100 units.
•	Upon entering its home platform reduce its speed to 40.
•	Stop the train (with brakes) when it reaches the end of the platform.
•	After waiting for 10 seconds restart the train's travel plan.
T3A2: To boldly model where no one has modeled before...
Extend your controller by a behavior similar to the controller in Tutorial 1. Instead of using the train standing on KH_ST_1 choose a train of your choice in the Kicking Horse Station that faces against the main traveling direction.
•	The train should travel to any free platform in the Inner Circle Station with a speed of 100 and against the main travel direction of the kicking horse track.
•	Upon entering the IC station the speed should be reduced to 40.
•	Once the train reached its target platform, stop it (with brakes) and wait for 10 seconds.
•	Subsequently, the train should return to its home platform the Kicking Horse Station (without changing its direction) with a speed of 100.
•	Equivalent to the IC station the train should reduce its speed when entering the KH station and wait for 5 seconds when its platform is reached.
•	Eventually, the cycle starts again.
 
•	Make sure that the trains do not collide!
•	If the KH train wants to enter the IC station but no platform is free it must wait until one is free!
•	Model this appropriately! Don't stop the train instantaneously!
T3A3: Important Thoughts
•	Now, after modeling a relatively simple controller with SCCharts, write down a couple of features (3 at minimum) that you have missed and/or consider mandatory/useful for implementing a more sophisticated controler. Sort your feature list according to importance and be ready to present your list at the railway meeting.
