Baggage storage in the lounge is only available for sleeper and (I'm not certain) BC passengers. Bags are stored in the lounge's conference room. When the lounge attendant stored my bags there last month, in the morning, she tagged the bags with our reservation, train, and roomette numbers, locked the lounge's door and told us we could get to our bags anytime--just ask her to unlock the door. When we returned, late afternoon, the door was unlocked and remained unlocked until we boarded the eastbound SL.
