On June 6, 1880, the enginehouse of the C&SV burned down, damaging the railroad's two locomotives and incinerated a baggage car.

[8][9] In 1888, Cooperstown and Charlotte Valley Railroad (C&CV) was incorporated, and they were authorized to extend their trackage to the lands of Matthew Ward in Davenport.

[7]: 187 The C&CV was formed by a group of brothers and businessmen, since Thomas Cornell of Kingston, had "procrastinated" since 1872 in extending his Ulster and Delaware Railroad (U&D) westward from Stamford to Oneonta.

In early February 1890, the C&CV tracklayers reached Davenport Center, while the graders resumed work east of Harpersfield.

[7] For the next several years, stagecoach service was provided between Kingston to Cooperstown, and it connected the railroad gap between the C&CV and the U&D.

On September 10 and 11, 1949, the post-World War II Freedom Train visited Cooperstown, attracting over 4,000 visitors.

[12] The sale took place, after Delaware Otsego was forced to sell their 2.6-mile (4.2 km) section of the abandoned New York Central (NYC) U&D branch at Oneonta, in favor of construction of Interstate 88.

[12] The condemnation of the section by the state of New York, saved the major cost of constructing a concrete I-88 highway bridge over it.

On one occasion, vandals released the brakes on several cars, causing them to roll southward and derail at the foot of the grade.

Metal remains of the wreckage can be found between the railroad right-of-way and the west bank of the Susquehanna River.

The final C&CV freight train operated in December 1987, and occasional equipment moves subsequently occurred on the right-of-way.

NRHS chapter volunteers performed vegetation removal and trackbed rehabilitation before the line was reopened for seasonal tourist excursion service between Cooperstown and Milford.

This locomotive had been purchased for $15,000 by the Museum from its owner, Chapter President Bruce E. Hodges, in prior years.

The Norfolk Southern Railway (NS), which obtained the mainline route that interchanges with the C&CV, refused to ferry it from Cooperstown Junction to Dearborn, due to alleged clearance issues and its heavy weight.
