Tim, an out-of-state friend, visited over the Labor Day weekend. He has never ran trains before. I handed him the HC and asked if he needed instructions. He looked at the screen for a minute and said "No, I think I've got this." A few minutes later he says "This momentum deal is cool." As our trains met at a siding he asks "Can you put two locomotives together on the same train?" Sure, I said. I cut off my train and pulled onto the main behind Tim's train. My locomotive in number 202. Take control and nudge it onto the back of your train. Once it's hooked then consist it with your locomotive I said. That's all that was needed. Tim figured out consisting, got it set up right, and had a train with a helper moving on down the line with no instructions whatsoever.
Mind you, Tim is a 60 year old guy not some young smart phone kid. He is as old school as they come.
How easy is RP when an ole timer can figure out how to run a train with helper without any instructions? And in short order. Eat you heart out DCC people!
