The Rincon Local comes north on alternating days up to Albuquerque, then returns south on the opposite days, switching the appropriate customer(s) along the way. They seems to come north from Rincon on M-W-F and return south on Tu-Th-Sa.

I gleaned some info from another site awhile back that stated the southbound empty autorack trains out of Albuquerque depart on Wednesday or Thursday afternoon or evening, destined for El Paso and interchange back to Mexico.

Haven't yet figured out the frequency of the southbound unit grain trains or the northbound unit tankers, but see them on occasion. There's a regular horn in the late evening hours that sounds to be headed north, but haven't investigated that either.

As noted, dark territory south of Belen.
