“ Recognizing then that the side track is for a public and not a private use, we come to the question whether requiring the railroad company to bear a part of the cost involves a taking of its property without compensation.
As a common carrier a railroad company assumes and must discharge the obligations which inhere in the nature of its business. Among these obligations is that of providing reasonably adequate facilities for serving the public. ”

“ Under the settled rule in Minnesota a side track such as is in question here is not merely a private siding, but 'additional trackage for public use.' If need be the right of way for it may be acquired by condemnation. It becomes the property of the railroad company and an integral part of its railroad system, and is wholly under its control. Besides enabling the public to get the products of the industry served, it is at the service of all who have occasion to use it and must be operated accordingly. ”

“ The money is not taken from the company and given to others, nor is the use of the facilities to be uncompensated. Like other property employed by the company in the transportation of persons or property, the facilities have a real bearing on the rates which it is entitled to charge. ”
