| On this section of track, eastbound trains of the same class had right over westbounds of the same class. Class was designated in the timetable. In this case 135 and 138 are both first class trains moving in opposite directions therefore 138 would be superior. Before 135 could occupy the mainline, he would have to have something on opposing trains of the same class. Second class or inferior trains opposing 135 would have to have something on 135. This train orfer gives First 135 the right of track from Columbus to Trammels (the beginning of CTC which took precedent over train orders). If second 138 got to Trammells and first 135 was still at Opelika, the dispatcher could move second 138 further eastward by setting up a meet, say at Camp Hill. The dispatcher would have to set the meet up with the superior train first. In other words, he would have to issue a train order to first 135 first before delivering one to second 138. Another safe guard. |
