The Pendleton depot is a red brick building laid in flemish bond. Shallow pilasters define each corner and divide paired win- dows. Walls are stepped out just above ground level. The hip roof is decorated with small gables at each end of the ridge. Typical of depots from the period, the roof has a double pitch and canopy.
Red pipe designed to look like terra cotta tile covers the roof.
Corbeled wood brackets support wide overhanging eaves to protect passengers, baggage and railroad workers from the weather. The building is rectangular with its long axis parallel to the tracks. The operator's bay extends outward along the track side facade giving the operator or agent an unobstructed view and access to the tracks to signal passing trains. Several ventilators, vent pipes and an electrical service ent- rance pole have been added to the roof, but in a careful manner that does not detract from the building's appearance. Although the exterior is largely intact, changes have occurred.
