The following trains are regulars at Black Butte. Most operate everyday, except as noted:

Through service on the CORP between Black Butte and Medford, OR was suspended on May 7, 2008. The last through northbound over the Siskiyous departed Black Butte on the evening of May 6, 2008. A CORP local is still based in Weed - coming up to Black Butte with loads and bringing empties back to the mill in Weed several times a week. Less frequently, trains operate north as far as Montague to interchange with the Yreka Western. The current economic downturn has made it unlikely that through service over the Siskiyous to Medford will be restored anytime soon.

*The ongoing recession has resulted in a significant reduction of traffic on the UP mainline in comparison to recent years. Several trains have been anulled, others operate on a more sporadic basis than in the past.

Northbound
IOASE This is an "Oakland (West Oakland Yard) to Seattle (Argo Yard)" doublestack train. It leaves Oakland on Sunday evenings, putting it through Black Butte mid-morning on Mondays. At times it can potentially run other days of the week as well but this has not been common lately.
MRVHK The "Roseville to Hinkle" mainly hauls empty Canadian Pacific cars headed back to Canada via Hinkle Yard in eastern Oregon. From Hinkle most of the train will continue north into Idaho, crossing the border at Eastport, and going on to Calgary. This train is often seen at Black Butte mid to late morning.
MRVPD This is Roseville to Portland/Albina Yard manifest train is now running as needed, maybe one to three times per week.
MRVPT This is a Roseville to Portland (Portland Terminal's Lake Yard) general manifest freight. May run less than daily.
MRVPW Roseville to the P&W (Portland & Western) Railroad. This trains runs to Eugene and then is worked and parts handed added to locals and handed off to the P&W north of Eugene. This train often stops to drop off or pick up cars at the CORP interchange in the Black Butte Yard.
ZLCBR The "Los Angeles (LATC Yard) to Portland (Brooklyn Yard)" hotshot usually runs five days a week (x Sundays or Mondays) and is often through Black Butte in the early evening. Mostly piggybacks, containers on flat cars, and some double stacks, usually up front and on the rear.
ZLCSE This is the symbol for a doublestack train from Los Angeles to Seattle. However, it does not currently seem to be running very often.

Southbound
I-BRLT This train started running in Spring, 2011. It is a Portland (Brooklyn Yard) to Stockton (Lathrop Yard) intermodal train. Right now it is running out of Brooklyn Yard on Saturday evenings, around 7-8pm - more or less using the same time slot the ZBRLT uses on weekdays. That puts it through Black Butte on Sundays, mid to late morning. If traffic increases, this train may start running out of Brooklyn on Sunday evenings as well.
QHKRV This is the "Canadian Pacific" train, mostly loads of wood, grain, and other products coming down from Canada via UP's Hinkle Yard in eastern Oregon. It terminates at Roseville where the cars are humped and then sent to various destinations. This is often a mid to late morning train through Black Butte. It often, but not always, has DPUs.
QPDRV This is one of several Portland to Roseville mixed freights that pass through Black Butte. It often has DPUs.
QPWRV This train is handed off to UP by the Portland and Western RR and goes to Roseville.
ZBRLC This is the "Brooklyn Yard (Portland) to Los Angeles (LATC Yard)" hotshot with mostly piggyback and COFC (containers on flat cars). The "Brooklyn" is usually through Black Butte mid-morning. It doesn't run out of Portland on weekends so we don't see it here on Sundays or Mondays.
