How should an assisting train reach a disabled train in ABS territory if they are traveling in the same direction?

In the context of ABS (Automatic Block Signal) territory, an assisting train approaching a disabled train that is going in the same direction is required to adhere to existing signal indications. Following signal indication ensures that the train proceeds safely and maintains the integrity of the signaling system. This practice helps to avoid collisions or other dangerous situations by ensuring that the train only moves when it is safe to do so, as indicated by the signals.

Safety protocols in train operations emphasize the importance of adhering to signal indications, which guide train movements based on the status of the track ahead. This is especially crucial in ABS territory, where signals are used to communicate block occupancy and ensure that trains do not enter occupied blocks.

The remaining options suggest either disregarding signals or not taking into account the regulated procedures that help maintain safety in train operations. For instance, proceeding without regard for signal indications could lead to unsafe situations, as it disregards the critical information provided by the signals. The options regarding receiving a Form D or contacting the Dispatcher add layers of confirmation but are unnecessary when the signal indications are clear and actionable. Following the signal ensures that the assisting train can safely navigate to the disabled train.
