So I just took the CZ EMY-SLC in a roomette. While there were lots of announcements about masks, actual safety is questionable. In the sleeper I was in, I could not believe how many people would go in their rooms and take their masks off while leaving the doors wide open. Around our room there were 3 rooms immediately adjacent to us that did this. The sleeping car attendant, who did always wear his mask, would pop into their rooms and chat with them. I think the requirement should be to keep the door closed if you don't want to wear your face covering.
The other thing is the way the diner works. I'm sorry but in an enclosed space like that, even with people at every other table, there is a major risk of COVID transmission. Combine this with groups talking loudly and laughing, that is unacceptable in my opinion. It's unsafe for even a masked crew, it's unsafe to walk through, and it's unsafe for other passengers. This would a be prime asymptomatic transmission situation.
Finally, the SLA let an unmasked man onto the train in Reno to help his friends get situated. He asked the SLA if he could before his friends boarded, and there was never any discussion about the fact he was entering the train without a face covering. The people he was helping were able bodied and he was just checking out their room, not helping with luggage. This behavior being tolerated was unacceptable in my opinion. Even masked I think it was inappropriate for him to board the train if he wasn't traveling.
We're taking the CZ back SLC-EMY on Saturday night, so wish me luck. I'm not going to leave San Francisco again until 2021 based on this experience. I've arranged a COVID test for three days after our return (luckily very easy to get in SF) and am already required by health order to quarantine for 14 days upon return anyways. Still, after seeing what COVID has done to a couple of my healthy friends, I am shocked to see such relaxed behavior on Amtrak.
