Alpha symbols now?

Has the railroad moved to these? There was some discussion on this a while back, but have not heard anything recently.

no

there apparently are alpha symbols for some run through trains like the UP/CSX UPS trains, but that is about it

apprently these are used to simplify interchange, but even then, these trains still have a csx train symbol

IE: Q100 I think is one of them

There are some on other RR for example MCSXLAW and MCSXGAL.

the question was about csx, not other railroads

For the most part it would make things a bit simpler.

I agree; if one knows the alpha codes it gives a person more "dope" on a given train, especially when it's not one of the regulars on the line. An example from down here:
I heard the DS talking to a RxxLS. Didn't get the origin letter code, but checked my timetable to find that this was a ballast train destined to Harlingen, TX [to upgrade the right-of- way, as it turned out].
