Some of the road's ALCO diesels were sold to a railroad in Colombia, and three (out of four, and one of these was wrecked) of the newer ALCO diesels built by and in storage with ALCO's Canadian licensee MLW (Montreal Locomotive Works) were sold to US Gypsum in Plaster City, California. Only one of these modern narrow-gauge diesels, the last narrow-gauge diesel locomotives built for a North American customer, was delivered to the White Pass. The five diesels sold to Colombia were not used there as they were too heavy, and were re-acquired in 1999 – one was nearly lost at sea during a storm as it broke loose on the barge and slowly rolled towards the edge.
