On my trip in the #422 sleeper last week, the attendant had a foam bucket of ice across from the coffee machine, juice boxes, and water bottles available all trip at the center of the upper level.
It is unfortunate that your SCA violated AMTRAK policy and Food Code by placing the ice out in public access. One of the nastiest bugs out there today, Norovirus, THRIVES in a cold environment and is not killed by alcohol gels. When large cruise ships get Noro outbreaks the prime suspect for transmission is ice and hand rails. Gee... do you see anything on a train that you can corelate to this?
Ice is considered food and thus must be handled with care and cannot be accessible to the general public unless there is a dispensing system that would prevent bare-handed contact with "ready to eat" food (ice). The attendant should be required to wash his/her hands and put on a glove before scooping the ice (though I dont know if this is enforced onboard.)
I know we all like the convenience of always available ice, but until AMTRAK retro-fits all cars with gravity fed ice dispensers, the policy of having ice available in the attendant's room for the asking is the safest from a public health standpoint.
Thank you for your concern but I'll take my chances with norovirus over the rather great inconvenience of having to find (and interrupt) the SCA every time I want ice. Also, Amtrak policy is not as you claim. Rather the manual says that ice will be avilable at all times in the ice container or something to that effect. In fact I've only seen one sleeper that actually had a built-in ice container. In all the others, there's simply a styrofoam ice chest with an ice scoop.
Also, how about a source on your claim that norovirus thrives in cold environments. Yes , there have been cases of norovirus being transmitted via contaminated ice but it's not at all common. And AFAIK all viruses reproduce more slowly at cold temperatures. "Survives", yes, but I doubt it thrives. But, hey, give me a source -- I'm here to learn.
Retrofitting with gravity ice dispensers: I'd be delighted but don't hold your breath.
Alcohol gel: it's actually not very effective against anything compared with soap and water. But what does that have to do with ice?
My advice is to use the scoop carefully so as not to get the handle into the ice and then leave the scoop outside the plastic bag, not inside it on the ice. And for god's sake if you're sick with something thaty might be norovirus, wash your hands throughly before handling any food stuff anywhere! If it's not fun to have on the train, it's even less fun on a two-flight transcontinental plane trip. I speak from experience.
Sorry to jump on you, but not having ice available is one of my few (very occasional) gripes about SCAs.
