Meet at Sais With an eastbound Santa Fe freight waiting momentarily at Sais siding, a westbound intermodal leaves the confines of Abo Canyon, New Mexico, and will soon pass it after negotiating a broad left-handed curve. This train on its way to a crew change at Belen, some 21 mile distant in the faint line of trees above the eastbound’s power. Leading the westbound on this pleasant May 23, 1991, morning is a Superfleet GP60M No. 115.
