You are allowed to leave cars in a siding without permission from the RTC if you are operating in ABS territory and you possess a track authority. True or false?

• A. True
• B. False
• C. Not sure
• D. Depends on the workload

Answer: (B)

In ABS territory, you still need explicit authority to occupy or use any track beyond what your current instruction covers. A track authority lets you move within a defined block, but it does not automatically authorize you to leave cars on a siding. A siding is a separate piece of track that can be used by other movements, and storing equipment there requires protection and approval from the RTC. Without that permission, leaving cars in the siding could create a conflicting occupancy or unsafe switch/signal conditions. So even with a track authority, you may not leave cars on a siding without RTC authorization. The RTC must issue the proper authority to occupy or protect that siding.
