Every railroad company or corporation organized under the laws of this state or doing business in this state, upon application in writing, shall provide reasonable sidetrack facilities and running connections between its main track and elevators and warehouses upon or contiguous to its right of way at such stations. Every such railroad corporation shall permit connections to be made and maintained in a reasonable manner with its sidetracks to and from any warehouse or elevator without reference to its size, cost, or capacity, if grain or potatoes are    or may be stored. The railroad company is not required to construct or furnish any sidetracks except upon its own land or right of way. Such elevators and warehouses may not be constructed within one hundred feet [30.48 meters] of any existing structure and must be at safe fire distance from the station buildings so as not to conflict essentially with the safe and convenient operation of the road. If stations are ten miles [16.09 kilometers] or more apart the railroad company, if required so to do by the commissioner, shall construct and maintain a sidetrack for the use of shippers between such stations.
