+ * Model railway simulation. Can simulate trains moving on a railway network. Features:
+ * <ul>
+ *     <li>allows creating different types of rolling stock: engines, train-sets and coaches</li>
+ *     <li>handles both straight tracks and switches</li>
+ *     <li>only supports deterministic rail networks</li>
+ *     <li>trains can be composed of many rolling stocks</li>
+ *     <li>fancy ASCII art of trains can be generated</li>
+ *     <li>collision checking is slightly simplified and operates on a rail-based model</li>
+ *     <li>large railway networks can be simulated quickly</li>
