The Cascades are not commuter trains (like Sounder in the Seattle area), there Amtrak trains.
My bad. I guess. It looks like a commuter train schedule to me.Several Daily & Monday thru Friday trains, both northbound and southbound:

Amtrak runs state sponsored commuter/corridor trains in various parts of the country.
Commuter service usually doesn't go past the 75 mile mark from the major market, and usually only has one major market served.
Amtrak Cascades is not a commuter train, it is a regional train just like the Lincoln Service in the Midwest or San Joaquin in California. There is a difference between commuter rail and regional rail.
However, some commuter rail lines are over 75 miles. For Example: LIRR Montauk Branch, LIRR Greenport Branch, Metro-North/NJT Port Jervis Line, NICTD South Shore Line, Metrolink Orange County Line, Metrolink Inland Empire-Orange County Line, Altamont Corridor Express, and New Mexico Rail Runner Express are all at least 85 miles.
