No, my point is that these two conditions aren't identical in some cases.  
In 18VA, a 2-train would score $0 between Lynchburg and Roanoke (the route
is invalid), whereas a 1G-train would score at least $50.

"A train" is not the same as "a 2-train".

However, this is just a warning from my side, as I'm currently not aware of
any games where it really matters.
