The company was renamed Tilcon Tomasso in 1979, when it was purchased by British company Thomas Tilling Ltd. Ownership changed to British Tyre and Rubber in 1984. Tilcon Connecticut (1990-present) 
The company's name was changed to Tilcon Connecticut in 1990 out of recognition of the company's extensive operations in Connecticut. Tilcon's operations in Connecticut were threatened by Amtrak's electrification project on the Northeast Corridor between New Haven and Boston in 1994. The company said its viability was threatened by increased Amtrak train service, which would force Providence and Worcester Railroad freight trains to run at night on a limited schedule. Tilcon's president said at the time that "It would knock us out of business or limit freight service to the point that we would lose hundreds of jobs." Facilities
