How far before a TSR is a caution board placed?

• A. 100 meters
• B. 250 meters
• C. 50 meters
• D. 500 meters

Answer: (C)

A caution board is placed 50 meters before a Temporary Speed Restriction (TSR) to provide adequate warning to train operators. This distance allows sufficient time to reduce speed appropriately in preparation for the TSR, ensuring the safety of both the train and its passengers as it approaches an area where speed limits change due to track work or other conditions. The placement of the caution board at this specific distance is part of safety protocols designed to enhance situational awareness for train crews. By providing this warning at 50 meters, operators can better manage their approach to the TSR, ultimately minimizing risks associated with sudden speed changes. In contrast, caution boards placed at longer distances, such as 100, 250, or 500 meters, could result in reduced effectiveness, as they might not align with the operational dynamics of trains and their braking capabilities, potentially leading to misjudgments or unsafe practices in approaching speed restrictions.
