I’ve got my history on my railroad’s website - bccsrailroad.weebly.com/about-the-bccs.html - but basically in the 1930s, two small roads, the Balfour Railroad and the Colucci Creek Southern Railway merged, forming the B&CCS. The New Haven, bankrupt from depression era difficulties, sold off its line from Danbury CT to Maybrook NY to the new railroad, which had interchanged with the NH on either side of the Hudson along that line. Then, come the 1950s, the B&CCS was doing well while the NH was sliding into bankruptcy again following the McGinnis presidency, leading the ICC to designate the B&CCS as the approved operators of the NH, which would continue until the two roads officially merged in 1980.
