What is an RVRO or RBRO? MTH Freight Sounds

I'll bet that is a UP train symbol that the Dispatcher is referring to. 

RoseVille to RenO freight?  But I thought UP used a five letter symbols for freights:

First Letter:  Type of train.

Letters 2 and 3:  Train's starting point.

Letters 4 and 5:  Train's ending point.

The UP, like all RR's have officail train symbols, but thy usually call them by their "nickname" or short names over the radio... It's just easier than spitting out all the numbers and letters of the real train symbol. The dispatcher is just telling the crew that they are waiting for another train to clear... if you know exactly what the letters are, I can find out.

Even though I work for BNSF and go to the UP everyday for a manifest train, and we have a specific formal train symbol, they still call us "Inbound Santa Fe" or "Outbound Santa Fe" over there. We've always been called the "Santa Fe" over there, even after the BN merge, and even after UP bought the SP.

Thanks folks.  I think that solves it.  I didn't know trains used symbols, I guess I always figured they would use their engine number on the radio.  Now that I know that it's likely a UP train symbol here are the likely candidates pulled from a pdf of Union Pacific Symbols.  Like Laidoffsick said, it is a short version because it's missing a character or two.

RB  Riverbank, CA (Stockton/BNSF)

RO  Rochelle, IL

or

RO  Roper Yard (Salt Lake City, UT)

RVRO stands for Roseville Roper.  Often the dispatcher will drop the M but the offical designation is MRVRO.  M stands for manifest, and Q will be used for high priority manifests.   At the time the recording was made, we had double track main line with ABS in Sparks Nevada which has since been converted to CTC on both mainlines.  We used track permits to work against the current of traffic before conversion to CTC.  Also the yardmaster control both mainlines, now the dispatcher in Omaha control the CTC.  Took a while for that operation to move smoothly.  Riverbank is in California but on the BNSF and when the BNSF trackage rights trains come through on the UP we use a different symbol than when on the BNSF. 

Greg,

Thank you so much for clearing that up!  I did a quick google search for Roseville Roper, and I got back a couple of youtube videos with a Roper Roseville (similar train going in the opposite direction?).  The video also mentions Donner Pass, so I'm guessing these are two large yards on opposite ends of Donner Pass?  Please tell me what ABS and CTC stand for?

Thanks again!

MRORV is the opposite train.  It's one of the manifest trains that doesn't go down the Feather River Canyon.  ABS stands for Automatic Block Signal and CTC Centralized Traffic Control.  CTC the dispatcher can control switches for sidings and ABS switches are hand throw.
