What must extra trains observe while moving quickly through junctions or tight points?

When extra trains are moving quickly through junctions or tight points, it is critical for them to observe proper signal indications. This is important for several reasons. Proper signal indications provide clear guidance on track conditions, routes, and potential conflicts with other trains or equipment in the area. The signals ensure that the train operates safely and within the rules governing railway operations. Misinterpreting or ignoring signal indications can lead to dangerous situations, including collisions or derailments, particularly in complex junctions where multiple tracks converge.

While speed limits and other regulations are key to safe operations, the emphasis on signal indications highlights the role they play in coordinating movement through potentially hazardous points in a rail network. Signal indications not only encompass the directives related to speed but also account for the overall safety protocols necessary for navigating junctions efficiently and securely. Therefore, observing proper signal indications is fundamental to ensuring the safe passage of extra trains through these critical areas.
