Hi everyone I'm new here and I apologize if these questions have been asked before so without further ado, here are my questions. Are the trucks on the DDA40X powered simulatneously by both engines s ( power from each engine going to both trucks.) or does each engine power a respective truck (Front egnine powers front truck and back engine powers back truck or back engie powers front truck and front engine powers back truck). Also can it be run with one enigne powering both trucks as a means of saving power when pulling light trains. I have tried looking online for the desired information but the closest I found was this ( https://www.quora.com/How-does-a-train-bogie-work" onclick="window.open(this.href);return false; ) but only mentions the DDA40X once and provides vague information on how the trucks work.
