Wyo. Stat. § 37-3-113 (2026)

and other facilities.

     (a) Every public utility shall afford all reasonable,
proper and equal facilities for the prompt and efficient
interchange and transfer of passengers, property, cars loaded or
empty, messages, service, or other facilities between the lines,
plants or systems owned, operated, controlled or leased by it,
and the lines, plants or systems of every other public utility,
and shall make such interchange and transfer promptly without
discrimination between shippers, passengers, carriers and all
persons either as to compensation charged, service and
facilities rendered or afforded. Every public utility operating
within the state shall receive and transmit without delay or
discrimination, any message, service, passenger or property or
facility of or from every other similar public utility with
whose line or plant or system a physical connection may have
been made. But this act shall not be construed as requiring any
public utility to give the use of its tracks or terminal
facilities to another public utility engaged in like business.

     (b) Nothing in this section contained shall be construed
as in anywise limiting or modifying the duty of a public utility
to establish joint rates, fares and charges for the
transportation of passengers, property, messages, service or
other facilities over the lines, plants or systems owned,
operated, controlled or leased by it and the lines, plants or
systems of other similar public utility, nor as in any manner
limiting or modifying the power of the commission to require the
establishment of such joint rates, fares and charges, such
public utilities have failed to agree upon such use or the terms
or conditions of compensation for the same, the commission may
by order direct that such use may be permitted, and prescribe a
reasonable compensation and reasonable terms and conditions for
such joint use. Said commission however, shall not direct or
sanction such joint use except in case of clear necessity.
