 Following suggestions by Clifford Hooker (1981) and Berent Enç (1983), John Bickle (1998: Chapter 4) argues that even the radical type of multiple realizability (in the same token system over time sense) is a feature of some widely-accepted historical scientific reductions. For example, it occurs in the reduction of classical equilibrium thermodynamics to statistical mechanics and microphysics. For any token aggregate of gas molecules, there is an indefinite number of realizations of a given temperature: a given mean molecular kinetic energy. Microphysically, the most fine-grained theoretical specification of a gas is its microcanonical ensemble, in which the momentum and location (and thus the kinetic energy) of each molecule is specified. Indefinitely many distinct microcanonical ensembles of a token volume of gas molecules can yield the same mean molecular kinetic energy. Thus at the lowest level of microphysical description, a given temperature is vastly multiply realizable in the same token system over times. Nevertheless, the case of temperature is a textbook case of scientific reduction. So even this radical type of token-token multiple realizability is no barrier in principle to reducibility. An actual case in science exemplifies it.
