Which signal is located in the engine control compartment?

• A. Cab Signal
• B. Bulletin Order
• C. Blue Signal
• D. Block Signal

Answer: (A)

The signal inside the engine control compartment is the Cab Signal. This type of signal is displayed inside the locomotive cab to inform the engineer about the route status and any speed restrictions ahead, so the engineer can respond promptly without looking outside. The other items aren’t located in the cab: a block signal is a trackside indicator showing block occupancy, a blue signal is typically used for protection or operational instructions outside the cab, and a bulletin order is a written directive, not a signal displayed in the cab.
