I'll be traveling on the California Zephyr soon. My wife and I will take small bags into the Roomette; however, I'll be leaving a larger bag on the shelves near the stairs on the 1st level (technically, not a "checked" bag).

Is there any way of locking the bag via a cable locking device (like used to lock skis)? Is there a post or anything that I can wrap the cable around?

Yeah, I know, I'm a worry wart! Just would feel safer if the bag is locked to the shelf.
