The large photoconductivity measured recently for trans-polyacetylene 50 ps after an exciting laser pulse was tentatively attributed to ``hot'' solitons because it depends little on ambient temperature from 10 to {~}300 K. We show, however, that the current carriers, which should include polarons as well as solitons, lose their excess energy of creation within less than a picosecond. Heating by the applied electric field should also be small but, interestingly, could be significant for fields only a few times higher than those used for the photoconductivity measurements.
