A train must not enter or foul ABS territory without?

• A. A proceed indication on a controlled signal OR Verbal permission of the Dispatcher
• B. Radio confirmation
• C. Signal from the Senior Conductor
• D. Written permit

Answer: (A)

Entering ABS territory requires explicit authority to occupy the track. NORAC rules say you must not enter or foul ABS territory unless you have a proceed indication on a controlled signal or you have verbal permission from the Dispatcher. A proceed signal shows the block ahead is clear and you’re authorized to enter. If the Dispatcher grants verbal permission, that also authorizes entry into ABS territory, which is important when signals are not giving a clear indication or for special moves. The other options don’t provide the necessary authority: a radio confirmation alone isn’t the grant of authority, a signal from the Senior Conductor isn’t how entry rights are established in ABS, and a written permit isn’t the standard method for entering ABS territory.
