No weekend trains? The saga of service on some NJ transit rail lines

Considering living in, or visiting Montclair?
Fine, just don't plan on traveling on any passenger train passing through towns such as Montclair, Bloomfield, and other towns on the Mountain/Boonton line.
If one is interested in traveling by public transit to the attractions in Montclair, such as the town's quality cinema (Clearview Clairidge Cinemas) or its jazz club, Trumpets Jazz Club-Restaurant, one's transit options are restricted.

The state of New Jersey, and NJ Transit, more particularly,
wish to lure people from cars, and make less of a carbon imprint?

Then, why are some lines, that travel through towns totaling scores of thousands of residents, shut down on weekends.

Transit should be available for weekend leisure, not simply for weekday commuting.
