17/3/2018 · The combined power and transit firm provided trolleys, fast interurban train lines, and electrical generation and distribution systems from Vancouver, Washington, to Salem. Stops on the interurban lines promoted the growth of towns like Estacada and Hillsboro , while giving farmers in Clackamas and Washington Counties easy access to Portland’s market.
The pallet motorized railway turntable is powered by 380v AC power. It is used together with rail transfer car and help the electric transfer car to change the running direction from 0-360 degree. It is one of choice of curved rails. To some extent, the turntable realized the rail turning, 90degree or 45 degree.
