Two Train ID Questions

[NSSpike]

Atlanta Inman dispatcher communication with two trains not heard before.
68X  and a 17D
The last X train through here was an 11X that I believe was a Chattanooga to Birmingham train. Rerouted through Atlanta due to conjestion.
The 17 D is a new one to me. Anyone know origin of these two trains?

68X was most probably a limestone train. DE Dan
