Some commuter rail lines around North America run frequent (hourly or better) and reliable service, all day long, 7 days a week. On the other hand, some commuter rail lines merely send a couple of trains in to downtown in the morning, and then a couple out to the suburbs in the evening, and don't provide much (if any) other service.
While these can both be useful, the former is a lot more useful than the latter, and it's not really valid to say a city with 2 commuter-only lines has as much service as a city with 2 all-day lines. So I'd like to know which commuter rail lines around the continent function in which manner.
This is what I'd like to do: List each commuter rail system in the US and Canada, and then describe whether it is an all-day-and-weekends service, or one that focuses only on commuters. Obviously they won't all be perfectly black and white; there may be some hybrids that are sort in-between, and some systems with multiple lines that each have different characteristics. Just do you best to try and fit hybrids into one category or the other. For the systems that are mixed, I'd like to list each line and describe the characteristics of each one.
Basically, I'd like to fill out the chart that I'm going to copy in the next post down.
To be clear, I am NOT talking about light rail, streetcars, subway, or anything that you might call "Metro rail" (unless you live in Austin). I am talking about trains that look like
this or
this.
