This Owen Firty Timber Co's latest acquisition - an On18 gas-mechanical, built to move logs on the company's triple-switchback. Named 'The Slug' (because it spends it's days slugging up-and-down the steep switchback), it has a Kato 11-103 power-truck, and a Digitrax DZ143 decoder. The purpose-built log-trailer rides on a re-gauged Kadee HOn3 truck.
