Where are the side inclines located in relation to the train system?

The side inclines are located at turnouts, which are specific points in the rail system where tracks diverge or converge. This design feature allows trains to transition smoothly from one track to another. It is essential for maintaining proper alignment and ensuring safe passage across different track configurations.

Turnouts are critical components of a rail system, facilitating the movement of trains in various directions while managing the flow of train traffic. Positioning side inclines at these locations aids in minimizing the risk of derailments and helps in providing a gradual change in elevation for the trains as they navigate the switches.

This choice underscores the design considerations in rail systems, where operational safety and efficiency are paramount. The other choices do not represent locations where side inclines would typically be found within the train system.
