The single-story wooden building is painted in traditional railroad mustard yellow and reddish-brown. Its simple yet sturdy hip-roof design is covered with corrugated tiles. The station front is adorned with a garden and a prominent "Pak Nam Pho" sign, a familiar landmark for travelers. This classic charm reflects its historical role as a century-old transportation hub connecting river trade with national rail lines.
