Two GMs and a Kenworth The lifeblood of St. Maries, Idaho, is turning timber into lumber and plywood—and the machines that haul it are seen at the 10th Street grade crossing in town. Logs head to the PotlatchDeltic mill behind a Kenworth, while a pair of GM GP9s sits nearby after taking finished lumber closer to market with a trip to Plummer on the St. Maries River Railroad earlier on September 27, 2021.
