Alex nice job, this answers alot of questions I had. I posted a thread about a week ago on the acela. You just made me want one more and more. Do you have the cars. If so while you have them could you do a video of the whole set in action. Also could you show an up close picture of the cars IR couplers and how they work. You say if this set is set up properly it works flawlessly. Am I hearing you correctly. Or as marty suggested do you need to install the wired tethers between the cars for the most reliable preformance? The IR issuse between the cars comes into play when the set atomaticaly tilts going around curves. Cant this feature be turned off via a switch on the top of the engine. Would this help in preventing the IR transmition issue between the cars? Thank for any info you could share with us as you have the set in your hands.
I'm sorry I don't have the passenger cars, I wish I did this way I could have tested them. To my understanding the features that the passenger cars have, would perform much better if the tetheres are wired.
If you like I can take a couple of close up pictures of the infrared tether between the engines.
