How should a train proceed when it enters a block with no governing signal?

• A. At regular speed until reaching the next signal
• B. At restricted speed until the leading wheels have passed the next governing signal of the end of the block system
• C. By stopping and waiting for directions
• D. By proceeding with caution without any speed limit

Answer: (B)

When a train enters a block with no governing signal, the appropriate action is to proceed at a restricted speed. This means that the train must move slowly enough to be able to stop short of any obstruction, which is critical for safety in the event that the block ahead is occupied or not clear. The requirement to maintain restricted speed continues until the leading wheels have passed the next governing signal or the end of the block system. This procedure ensures that the crew has time to react to any unexpected circumstances or conditions in the block ahead, such as another train or maintenance work. By moving at restricted speed, the train can operate safely within areas where the signaling system is not actively providing guidance. This rule is vital to prevent accidents that could result from improper speed in areas of uncertainty.
