When the switch lever on a GRS machine is positioned all the way out, what direction is it set to?

When the switch lever on a GRS (General Railway Signal) machine is positioned all the way out, it is set to the reverse direction. In the context of railway signaling and operations, the positioning of the switch lever is critical for controlling the movement of trains and ensuring safe operations on the tracks.

The term "all the way out" specifically refers to the position that engages the switch to direct train movements backward, or in the reverse direction. This understanding is crucial for tower operators as it indicates the track setting for incoming or departing trains. Knowing how the lever positions correspond to train movement helps in maintaining efficient and safe operations within a rail yard or along a track.

The other options do not apply in this scenario, as they describe different settings that do not correspond to the configuration of the switch lever when it is pulled out to the maximum extent. Understanding these distinctions is vital for any operation involving track switches and ensures clarity in communication and execution of train movement instructions.
