I am interested in the Aristocraft HO Train Engineer. I run track power with an Aristocraft 10amp Ultima and a track side TE as a throttle. I only have a simple loop and run 1 loco at a time. I'm planning an expansion in the spring and would like to run multi locos simultaneously with a TE in each. By choice, I run mostly small stuff so a HOTE seems to be a good alternative. I've researched MLS but all topics I can find use the HOTE with battery power. Is there anything special I'd have to do to power the HOTE from the rails and use it on board for a throttle?
