The OP's statement was "a typical comuter schedule", that is a schedule that
is entirely, or predominantly tidal in nature (in in the morning, out in the
evening), as opposed to a transit-like schedule, one that is high frequency,
stop at all stations, 
in both directions all day.  Such schedule philosophies can be applied to
heavy rail, light rail or indeed buses.  Terms "heavy rail" and "light rail"
are not particularly meaningful anyway as they are marketing, not technical
terms.  The same vehciles, 
eg Stadler GTW, operate on both "heavy rail" and "light rail" in different
locations.
