On my RK SP Heritage unit, I'm trying to understand what the tower is saying in the first part of the Freight Sounds. Here it is.
Tower:
"Tower, go ahead"
Engineer:
"We're sitting at the crossover, over"
Tower:
"There's an RVRO that's going to be crossing in the dark. When that's complete, I'll give you a track permit to crossover and come get your turnover"
My question is, what is an RVRO or maybe it's RBRO. In any case google turns up nothing for either one. The only close thing I could find on my google search is a mention of a Union Pacific MRVRO in youtube. However, they don't say what the acronym stands for. Any ideas?
