Where should caution signals be secured due to the motorman's cab position?

The correct positioning of caution signals in relation to the motorman's cab is critical for safety and operational efficiency. Securing caution signals on the right side of the track aligns with the common practice in rail systems where the motorman's cab typically faces toward the direction of travel. This positioning allows the motorman to have a clear line of sight to the signals without any obstruction.

By placing caution signals to the right, it ensures that the motorman can observe these indications as they approach, facilitating timely responses to warnings and ensuring the safety of the train operation. This is especially important in situations where quick action is required based on signal indications, such as slowing down or stopping the train.

Understanding the correct placement of signals enhances not just the individual motorman's ability to operate safely but also the overall efficiency and safety of the train system.
