Surface Transportation Corporation
The Surface Transportation Corporation was the bus-operating subsidiary of the Third Avenue Railway in New York City which operated under that name following the conversion of the streetcar lines in Manhattan and the Bronx to bus service between March 1941 and August 1948. On December 17, 1956, the corporation was bought by Fifth Avenue Coach Lines, Inc. (formerly New York City Omnibus Corporation) as part of its acquisition of the Third Avenue Railway, and its routes placed under a newly created operating subsidiary, Surface Transit, Inc.
