Connecticut has the ability to double its freight service capacity in central Connecticut if millions of dollars are spent repairing the system, but upgrading to passenger service is cost-prohibitive, a new study has concluded. Total costs for upgrades range from $140 million for Class 2 rail, with speeds of up to 25 mph, and $170 million for Class 3 rail, with speeds of up to 40 mph. But adding passenger service to Class III rail could cost between $410 million and $530 million, the study found.
