In the argument, Einstein employed a Carnot engine with two heat reservoirs, denoted by Uo and U and originally 'at rest' with the same (rest) temperature To, to illustrate how heat is transferred between them, if U is accelerated to a velocity adiabatically along with an auxiliary machine.
Einstein adopted an auxiliary thermal reservoir rather than an ordinary Carnot engine such that the machine absorbs heat from Uo without volume change.
Thomson looked at the first, isothermal stroke of a Carnot engine.
