You should seriously be considering vacations centered around looking up at the night sky. It's worth a trek to see brilliant views of stars you'll never see in the city. That's probably doubly true as the COVID-19 pandemic continues to position us for social distancing over the long term.
A train ride certainly isn't going to provide the necessary distancing you're looking for, but you can always plan ahead. The Nevada Northern Railway has announced its Star Train dates for 2021. This ride out into Nevada's dark skies will provide the opportunity stargaze as you've never stargazed before. (And, look, it'll be pleasurable even if you've experienced dark skies before.)
