In which direction should a trackman walk when inspecting a section of track?

Walking opposite to the direction of traffic is the recommended practice for a trackman inspecting a section of track. This approach is essential for safety reasons, as it allows the trackman to see any oncoming trains and be aware of their approach. By facing the direction from which trains are coming, the trackman can respond quickly in case of an emergency, such as signaling for the train to stop or moving out of the way. It also gives the trackman the opportunity to assess the condition of the track while remaining vigilant about the safety of oncoming rail traffic.

The other options, such as walking toward the direction of traffic, in a circular pattern, or diagonally across the track, do not prioritize safety in the same way. Walking toward the traffic would mean the trackman could not see any approaching trains until they are very close. Circular patterns or diagonal movements don't provide the same line of sight and situational awareness necessary for safe inspections. Overall, walking opposite the direction of traffic enhances the trackman's ability to conduct their duties safely and effectively.
