I noticed both. He was asked about the Acela project by someone who might have been in the know already, or so it seemed to me. But he said this project won't be leading to anything being issued until 2021, shortly before the prototype is retired, because they have a VL project going for 2020. He also said that in both mechanical and electronic terms any new Acela would be simpler than the original. Well, it would have to be.
I'll be interested to see what if anything happens about this. It has always seemed to me that the tooling for the Acela cars must have been a considerable investment and Lionel would want to "recycle" it at some point. But more to the point they are the finest detailed passenger cars ever produced in 3rail O scale, IMHO. The door opening and serial data issues are well known and it seems to me that they could be overcome. After all, there have been some more recent subway sets with a door opening feature that functions correctly.
I have the original Acela sets BTW.
On user-programmable Legacy sounds he was much less definite as in, simply not possible under existing Legacy system architecture but they were looking at the possibility somewhere down the pike. In other words he wasn't ruling it out, or that's my take on this point.
