The cars are still under warranty and any problems are CRRC's responsibility, the T has said. Conti answered questions Monday prior to an event at CRRC's $95 million Springfield factory featuring U.S. Rep. Richard E. Neal, D-Springfield, Mayor Domenic J. Sarno, state Rep. Bud Williams, D-Springfield, and City Councilor Olando Ramos. The occasion was the celebration of a compromise in Washington brokered by Neal that will allow CRRC to continue signing new contracts and bringing more business to the Springfield factory.
