C. and O. replaces 1850 Blue Ridge tunnel
Need for larger tunnel to permit passage of more powerful engines and large loads prompted construction of 4000 ft tunnel through Blue Ridge Mountains on C. and O. Ry; it will replace tunnel, largely unlined, started in 1850 and in service for 84 yr. (See also and O. v 131 n 1 July 1 1943 p 18-20; Compressed Air Mag v 48 n 9 Sept 1943 p 7182-5)
