Welcome to the fourth installment of my layout videos. This time we concentrate on my vintage Lionel operating accessories. Most of these were produced in the mid-fifties, making them over fifty years old! They load and unload lumber, culverts, ice, coal, milk cans, cattle and oil drums.
The last scenes feature two projects that I built from scratch. The school playground is powered from below by three small gear motors. Note that the two swings run independent of each other.
The lift bridge is constructed using Erector girders, pulleys and motors. The moveable span is an Atlas single track Pratt Truss bridge. Two Erector motors connected together on top of each tower drive a shaft that rotates six pulleys. Cables that run over the pulleys are connected to the bridge span on one end and a counterweight on the other. Power for the track on the bridge and LED lighting is supplied by two twisted pair wires that raise and lower with the bridge. The weighted wires descend into the the bridge abutment. Each pair of motors is controlled by a variable power supply to help keep them in synchronization so the bridge is kept level. The bridge spans 40 inches wide and rises to a 74 inch clearance. It connects my main layout with a three track siding that is 18 feet long.
