Six fixed routes (with deviation on request) provide week-round service to the towns of Brooklyn, Killingly, Plainfield, Putnam, and Thompson.

With advance reservation NECTD also offers dial-a-ride service to the general public and door-to-door to select elderly and disabled persons.

Dial-a-ride and door-to-door service is available to all towns served by NECTD's fixed routes as well as to Canterbury, Eastford, Hampton, Pomfret, Union, and Woodstock.

NECTAR began as a pilot program by the Northeastern Connecticut Regional Planning Agency and was funded by the Federal Highway Administration.

NECTAR began as a free service offering door-to-door transport for residents of Brooklyn, Canterbury, Eastford, Killingly, Plainfield, Pomfret, Putnam, Sterling, Thompson, and Woodstock.

[9] Following Pomfret, Putnam, and Sterling's removal, NECTD's fixed route and car-/vanpool services were only planned to serve Brooklyn, Canterbury, Eastford, Killingly, Plainfield, Thompson, and Woodstock.

[12] In November 1980 Putnam's Chamber of Commerce paid for the town to re-enter NECTD citing sales losses that occurred since their withdrawal.

[14] On February 13, 1982 a ceremony was held in Brooklyn to commemorate the arrival and implementation of Steyr City Buses into the NECTD fleet.

[10] Following a donation from the Putnam Chamber of Commerce in December 1980, NECTD's single route was split into two:[16] In February 1981 a program designating free fares once a month was introduced, intended to increase ridership.
