Train 190 has come out of Corpus Christi and is stopping at the south end of town on October 25, 1977. Missed the last unit number, but the rest are 1926, 1944, and 1915. Notice that each of these GP18s are riding on old Alco trucks. These engines were built in 1962 and used the trucks from Alco RS3s sent to EMD in trade. All of these units were put into storage around 1981 and scrapped in 1984. Disk 103
