The retreating "colorados" boarded trains that were waiting for them at the station and left the area. Huerta's troops, which were running low on supplies were unable to engage in immediate pursuit. At this point, Orozco attempted a variation on a tactic that he had successfully employed at the first battle of Rellano. There, Orozco had a locomotive filled with dynamite (the "loco loco" or the "máquina loca"), which he then sent against incoming federal troops. This time, he ordered his men to mine the rail tracks behind them, in the hope that Huerta would be too eager to pursue him to take proper precautions. Unfortunately for Orozco, one of the mines detonated prematurely, damaging only a railcar with coal and also alerting Huerta to the possible danger. As a result, Huerta proceeded more carefully, and his engineers managed to find all the remaining mines placed by Orozco's men.
