| TSRR Southbound Local Freight Train ( Columbia, Tn. to Florence, Al. Turn ) passing through Ethridge, Tn. on their way to interchange with NS in Florence, Al. TSRR interchanges with CSXT in Columbia, Tn. & NS in Florence, Al. The few times I've visited the TSRR the northbound goes north to Columbia, Tn. from Mt. Pleasant, Tn. early in the morning to interchange with CSXT & heads back south in the afternoon to Lawrenceburg, Tn. where the 1st crew ties down, then another crew comes on duty around 6:00 pm at Lawrenceburg, Tn. to take the train on to Florence, Al. to interchange with NS |
