I had the set and sold it to Alan (Leavingtracks) and he asked for new traction tires. I did this when the Legacy set was announced. I live a stones throw from the Boston to New York main line. I see an average of two Acela trains every day. I hear them all all day long blowing the horn. I have many Acela trips under my belt and love the train. I advise every train lover to put it on your bucket list. I have an Amtrak station (RT 128) in my town. After the Acela leaves the station heading down stream it cranks up to 150 MPH. Very smooth ride. Enough of that and back to the model.
The big headache is the IR transmission line at the couplers. Going through curves, many times communication is lost. The cars behind the communications break at the IR co silent and dark. I have an S curve on my main under the catenary and it happened every time. Thank God for AUX-1-0. After learning about the insides of the train I have done a few sets by replacing the IR and going to a male-female plug set. All the communication issues are now gone. The board sets inside the Acela are modular and not an issue. The operating doors are an issue. I first purchased the train as it was advertised with operating pans. Yes they operated but would not hold the live wire. They flopped around like a wet noodle.
We should see the Acela again but the highly updated Acela. We are in luck with Ryan Kunkle working with Lionel and big Mike. Ryan will make us happy. I have some information on how things will be but am not able to converse about it as it belongs to Lionel. If you have a current Acela, it is good property if you want to take time to dump the IR and hard wire it with plugs. Do not try to put traction tires on unless you have lots of time. Lionel charged $100.00 to do them and it was worth every penny. I will never do another.
If you are going to do the rewire, the IR sensor has two wires to it. The wires are ground and serial. Pay attention to the path of the wires and have fun.
One thing I left out is the Lionel recordings are one hundred percent accurate with the real Acela.
