Harlan F. Stone,
Broad River Power Company v. South Carolina ex rel…
“ It was there held that, where a railroad serving the public is owned and operated by a corporation which also conducted a private business, it is the business of the railroad and not the entire business of the company which determined whether the railroad franchise may be abandoned as unprofitable. The private business was not devoted to a public use or a part of the public franchise. Nor, as petitioners contend, are we here concerned with the rule that a public service company may not be compelled to serve, even in a branch of its business, at a rate which is confiscatory. ”
