Here in Boston a lot of the commuter rail cars are double decker. I guess it’s an upgrade to carry more people rooms but a better upgrade would be running more trains. That costs money though
Like other people said, I don’t know about subway. You want to be quick on quick off. I don’t usually even sit (even when there’s room )
Not at all. The rules were developed over time as the internet expanded from a handful of us research institutions to the global presence it is today. As other people in this thread mentioned, the present country code top level domain rules were developed from fiascoes like .su and .yu. Now they do have solid rules: they should follow them, regardless of corporate speculation and profiteering
