The line was operated as a for-profit company from 1895 until 1933 between the Maine towns of Wiscasset, Albion, and Winslow, but was abandoned in 1936.

Today 3.5 miles (5.6 km) of the track in the town of Alna has been rebuilt and is operated by the non-profit Wiscasset, Waterville and Farmington Railway Museum as a heritage railroad offering passenger excursion trains and hauling occasional cargo.

The line was reorganized in 1901 as the Wiscasset, Waterville and Farmington Railway following the inability to negotiate a crossing of the Belfast and Moosehead Lake Railroad near Burnham Junction.

[3] The museum runs 2 ft (610 mm) gauge steam and diesel locomotives and other historic equipment, and has other pieces on static display.

[4] Milepost 0: Wiscasset - Transfer yard largely built on pilings over the Sheepscot River estuary including a wharf, passing siding, interchange tracks with the standard gauge Maine Central Railroad and spurs serving a creamery and a grain warehouse.

A 3-stall enginehouse and turntable, a long coal shed, a large 3-track car shop, two storage sidings, and a water tank were north of the Maine Central diamond.

The railroad was within a relatively steeply incised portion of the Sheepscot River valley between Head Tide and Whitefield.

Milepost 17.4: North Whitefield - Agent's station building of standard design with a southbound spur serving a potato warehouse.

Milepost 20.4: Cooper's Mills - Agent's station with a passing siding and a southbound spur serving a potato warehouse.

Milepost 28.2: Weeks Mills - Agent's station building of standard design with a separate shed-roofed freight house, a covered water tank, one or two passing sidings, a wye for the branch to Winslow, and two southbound spurs for a potato warehouse and a cannery.

Milepost 32.9: Palermo - Agent's station building of standard design with a passing siding and a southbound spur serving a potato warehouse.

Milepost 38: China - Agent's station building of standard design with a southbound spur serving a potato warehouse.

Milepost 43.5: Albion - Agent's station building of standard design was subsequently modified to add a second story with living quarters.

Milepost 31.5: South China - Agent's station building of newer design with a northbound spur serving a potato warehouse.

Milepost 36.5: East Vassalboro - Agent's station building of newer design with a northbound spur.

Rails were removed from the Winslow end of the branch in 1912, but the railroad provided freight service as far as North Vassalboro for a few more years.

These two new outside-frame Baldwin engines moved most main-line trains until they were damaged in the 1931 Wiscasset enginehouse fire.

The Wiscasset car shop completed a number of rebuilding projects starting with the conversion of six of the original flatcars to boxcars during the first year of railroad operations.

[13] Combination #6 was converted to an express car by removing interior features and placing protective bars across the windows.
