NS Frazer/Malvern action

The old Trenton cut-off is a mere shadow of what it used to be. After King of Prussia, going west, the service is minimal. My question is how minimal? There is usually a train parked on the Rt. 30 (Lancaster Avenue) overpass in Malvern, but it appears to run twice a week.

Can anyone enlighten me to NS's schedule?

There is a Coatesville job out to the ISG mill... I've occasionally seen it in the morning around 8:00 crossing the bridge over the Schuylkill Expway headed west... uses an old CR caboose as a shoving platform for the reverse move...not sure how many days a week she runs. Have heard symbols H3A and H2A used for these trains.
