What equipment might be used to assist in confirming switch positions?

Visual signals and communication devices are crucial in confirming switch positions because they provide real-time information and feedback regarding the status of switches on the rail network. These devices, such as light signals or railway communication systems, enable operators to clearly see and understand whether a switch is set to the correct position for train movements. This confirmation is vital for ensuring safety and preventing accidents, as an incorrectly set switch can lead to derailments or collisions.

While track tools may aid in physically adjusting switches, they do not directly confirm switch positions. Speedometers measure the speed of trains and are not relevant when determining switch settings. Fuel gauges are primarily concerned with the fuel levels of locomotives and do not play a role in the operation or confirmation of track switches. Therefore, visual signals and communication devices stand out as the essential equipment for accurately confirming switch positions.
