Glenbrook is a 2-6-0, Mogul type, narrow-gauge steam railway locomotive built by Baldwin Locomotive Works in 1875 for the Carson and Tahoe Lumber and Fluming Company's 3 ft (914 mm) Lake Tahoe narrow-gauge railroad.

At the summit, the logs and lumber were put in a flume which carried it to the south end of Carson City.

[2] That winter, the railroads at Glenbrook and Bijou, along with most of the towns, were moved to Tahoe City, California, on the west shore of the lake.

The Bliss family leased the LTR&T to the Southern Pacific in 1925, and the line was converted to standard gauge effective 1 May 1926.

In 2021, The Glenbrook visited the Cumbres and Toltec Scenic Railroad for their Victorian Iron Horse Round Up Celebration with the Eureka locomotive.
