I've been able to track the status of rail car TTGX985818, using the Norfolk Southern automated Intermodal telephone line providing the following updates:
09/09, 12:00 AM, Shelbyville, MC Ramp 8P
09/10, 8:00 AM Louisville, KY
09/11, 8:00 AM West of Louisville, KY (exact location inaudible)
09/12, 8:30 PM Princeton, IN
Finally seeing light at the end of the tunnel since my rig sat at Shelbyville Ramp 8P since 06/23.
