The model of dissipation studied by Castro Neto and Caldeira [Phys. Rev. Lett. 67, 1960 (1991)] is reexamined. The main results for transport are derived in a simple manner without the use of Feynman path integrals. By means of a unitary transformation, a connection is made between the model and a model previously studied in the field of quantum dissipation. Lastly, extensions of the model are discussed.
