The normal position of a derail located on a siding is in the non-derailing position. This is designed to prevent a train from inadvertently entering a track that is not intended for travel, ensuring safety. In the non-derailing position, the derail is aligned to allow traffic to pass over it without redirecting the train onto the siding. This is crucial in maintaining control over the movement of trains and preventing accidents.

Other options could imply that the derail is set in ways that may lead to unintended consequences. For example, being lined and locked might suggest a different state of readiness that does not necessarily align with safety protocols for regular operations. Similarly, an open position for sorting cars or an engaging position would imply that trains could be diverted or derailed, which contradicts the purpose of the derail's normal state on a siding. Hence, the non-derailing position emphasizes safety and operational integrity in train dispatching.
