BNSF C44-9W 4806 is the final unit of a matched set of "pumpkins" on this intermodal which is entering Abo Canyon, NM following on block of the 7494 (previous image) on January 13, 2009. When this train leaves the canyon near Sais, another train will already be waiting to head eastward through this bottleneck.
