I vote for "R" and here is why...
GT - Still in use regionally
T - Used for IT Trucks regionally
X - Used regionally
G - Looks too much like a "C" at 100mph.
O - Looks too much like a "C" at 100mph
U - For the *next* class.
Yes, I know that there should be no mistaking ITC and ITO cars on the track, but thats not the point. Workers and T/S want everything to be clear, and in many fonts an O and a C are going to just be way too close.

Wouldn't the "R" look too much like a "B" at 100mph?

Bill... that's PERFECT! Exactly what I was thinking...
I think I'd pronounce it "IT-Cha-Ching..." :119:
