In the event of a slow speed order, what should the engineer look for?

When assessing a slow speed order, the engineer should look for triangles alongside the MAL bar. In train operations, particularly in signaling systems, the presence of triangles is an essential indicator of the conditions under which a train should operate. These triangles signify specific restrictions or cautionary measures that the engineer must observe, ensuring safe transit at reduced speeds. Proper identification of these visual cues is crucial for maintaining safety standards and operational efficiency during slow speed scenarios.

The other potential cues mentioned, such as clear track indicators, green MAL bars, and red flags, serve different purposes within the signaling framework and indicate various states of track and train conditions that may not directly correspond to a slow speed order. Understanding the significance of each signal and its implications is vital for engineers to navigate safely and effectively during their operations, emphasizing the importance of recognizing triangles alongside the MAL bar in the context of slow speed orders.
