(a) This section applies only to an authority confirmed before July 1, 1985, in which the principal municipality has a population of less than 1.3 million.
(b) The authority may hold a referendum on whether the authority may operate a fixed rail transit system. At the election the ballots shall be printed to permit voting for or against the following proposition: “The operation of a fixed rail system by (name of authority).”

(c) The notice of an election called under this section must include a general description of the form of the fixed rail transit system, including the general location of any proposed routes.
(d) If a majority of the votes cast are in favor of the proposition, the authority may build and operate the system as provided in the notice for the election. If less than a majority of the votes cast are in favor of the proposition, the authority may not expend funds of the authority to purchase, acquire, construct, operate, or maintain any form of a fixed rail transit system unless the system is approved by a majority of the votes cast at a referendum held by the authority for that purpose.
(e) A subsequent referendum under Subsection (d):
(1) may be held more than once;
(2) is held in the same manner as the initial referendum; and
(3) must be held at the general election in November of an even-numbered year.
(f) A referendum on a proposal to expand a system approved under this section may be held on any date specified in § 41.001, Election Code, or a date chosen by order of the board of the authority, provided that:
(1) the referendum is held no earlier than the 62nd day after the date of the order; and
(2) the proposed expansion involves the addition of not more than 12 miles of track to the system.
(g) This section does not require the authority to hold a referendum on a proposal to enter into a contract or interlocal agreement to build, operate, or maintain a fixed rail transit system for another entity. Notwithstanding Subsection (d), the authority may spend funds of the authority to enter into a contract and operate under that contract to build, operate, or maintain a fixed rail transit system if the other entity will reimburse the authority for the funds.
(h) A referendum held by a political subdivision, the authority, or an entity other than the authority at which funding is approved for a fixed rail transit system is considered to meet the requirements of Subsections (d) and (e) and § 451.3625 if the notice for the election called by the political subdivision, the authority, or other entity contains the description required by Subsection (c). The referendum may allow for financial participation of more than one political subdivision or entity. The authority may only spend funds of the authority if the referendum authorizes that expenditure.
