- Marine walking beam engines built in the mid-nineteenth century were massive pieces of machinery towering 40 to 50 feet high from the bed plate to the top of the beam and weighing many tons. This model is a true working model, complete with condenser and air pumps. These original engines typically ran very slow, in the range of 30 RPM, which made them ideal for turning the large paddle wheels on side wheel steamers. Our model drawings include the feathering paddle wheels that would have been on the side wheel steamers of the time.
