Marklin 6071 IR Control VariantsUnitPrice_number_168.99 The frog for these turnoutsThis Infrared Controller (handheld transmitter) 6071 is capable of allowing four person wireless walk around control. These units are no longer manufactured but occasionally can be found. This IR Control is to be used in conjunction with Infra control 80 and cannot be used directly with 6021 Control Unit.
