Who must take the siding when PSGR Extra West meets Track Car Extra East?

The correct answer reflects the operational protocols that govern the meeting of trains on the rail network. In scenarios where a passenger train (PSGR Extra West) encounters a slower-moving train, such as a track car (Track Car Extra East), the passenger train generally has priority. This is rooted in the established right-of-way rules, where passenger operations typically take precedence due to their scheduled nature and the need for efficiency in public transportation.

In this context, PSGR Extra West would be required to have the other train take the siding to ensure that it can pass unimpeded. The siding is a section of track that allows one train to pull off the main line, letting the other continue uninterrupted. This practice is crucial for maintaining the efficiency and safety of train operations, particularly in busy rail networks.

Understanding this priority system is essential for ensuring the safe and effective coordination of various train movements within the rail infrastructure.
