Original design PacificThis early design had a number of unique features. There was power pickup from the pilot truck and trailing truck, and from each axle (1 wheel) on the tender, as well as the drivers. (Aristo, you need to do this again).The loco had puffing smoke, and smoke from the cylinders. This did not work that great, and was not that reliable.There were lights in the firebox.The motor block pre-dates the current "prime mover" design. The wheels seem to be made of something else too, not as good as the current metal. The picture below shows some of the electrical connections with the boiler removed. Below, the smoke box is removed. This loco has been modified by R.J. Deberg to use the new style "prime mover" smoke unit. Below, you can see the modification to the smokebox to accommodate the new smoke unit. Smoking!
