In 2006, Lake County government contracted with Modoc Northern Railroad for railroad operations. Modoc Northern's lease was terminated in 2009, and was replaced by a lease to Frontier Rail, which established the Lake Railway as their operational unit.
Subsequently, Union Pacific leased operation of their tracks between Alturas and an interchange with UP at Perez, California to Lake Railway.

Frontier Rail and Lake County had a falling out in 2016, and by the end of 2017 the county had replaced Frontier with operations by newly-formed Goose Lake Railway, managed by Nexxt Logistics.
