Three things that some people in this thread don't seem to understand:
1. There aren't enough R62As for the to become 100% R62A
2. Just because the R142As are going to come from the doesn't mean that the R62As have to go there
3. @ junjun798, that article that you keep citing as evidence supporting your point makes no mention of whether the R62As are going to the or the . We still have no idea where you learned that from.
Look, the "cool" railfans who don't care about car assignments can call me a foamer, but I'll admit that I do find this topic interesting and I do have certain biases to certain trains being on certain lines. Unlike some people though, I won't try to predict anything or act like I know more than I do. I'm just trying to figure out what would be a logical solution for the R62As and R188s.
