The restored 15-ton switch engine is the museum's newest exhibit. Manufactured in 1945 by the Brookville Locomotive Works, the locomotive had been delivered to the Elk Tanning Company's tannery at Wilcox, Pennsylvania. The diesel powered "switcher" moved cars of hides and hemlock bark on the tannery sidings until the 1960s when the tannery was abandoned. The locomotive, together with other equipment and machinery, was sold to a local salvage company. The switch engine remained on their lot for almost 40 years until it was discovered by employees of the Pennsylvania Lumber Museum. A grant from the Lumber Heritage Region of Pennsylvania to the museum volunteers funded the restoration.
