East Layup signals are protected by what type of signals at both ends?

• A. Protected on the east and west ends by high signals controlled by JCC
• B. Protected on the east and west ends by low home signals controlled by JCC
• C. Unprotected signals
• D. Protected only on the east end by low signals

Answer: (B)

The key idea is that layup areas need protection from movements approaching from both directions. In this setup, both ends of the East Layup are protected by low home signals that are controlled by JCC. The low home signal type is the specific signal used in this environment to guard the entry to a block in yard or layup operations, providing a clear, standardized stop indication for trains moving toward or away from the layup. Having these signals at both ends ensures that no movement can enter the layup while the block is occupied or another movement is not cleared, regardless of direction. High signals are not used here, and having protection at just one end would leave the other end vulnerable. Unprotected signals would fail to provide the necessary safety for yard operations.
