It regained its independence in 1973 after the NH was absorbed by Penn Central and has since grown to become a major regional railroad in southern New England. 2205, a GE U23B ex-CR 2790, and 2215, a GE B23-S7 which was the first Super-7 rebuild, were at the Worcester MA engine house. 5 October 2001. - mike-walker
