@TM Terry posted:As best I can find, Schenectady in 1928 only made five 4-6-6T's, all five going to Boston and Albany (#400 - 404). And I can only find that #402 went to NYC and numbered 1297.
Were there any more 4-6-6T's made? And did any other railroads operate any of these 4-6-6T's?
Several authoritative reference books on the New York Central and Boston & Albany railroads refer to the five B&A D-1a 4-6-6T engines as the "biggest," "heaviest," and "most powerful tank engines" made in America. The B&A also had eighteen 2-6-6Ts. The New York Central & Hudson River Railroad had 2-4-4Ts. The Central Railroad of New Jersey had twenty-five 2-6-2Ts and five 4-6-4Ts. Illinois Central had double-ended 2-4-4T engines in Chicago suburban service and also one 2-6-4T. The New Haven Railroad had several types of small double-ended tank engines built prior to 1900 but nothing with a 4-6-6T wheel arrangement or comparable to the Boston & Albany 4-6-6Ts.
