You mean, like this one?
Serious or not, it would be cool. But there's not a lot of room inside for Lionel's high end electronics that a lot of guys want. BTW, this one is my Bill's Train House kit I assembled in 2004. With an all but bullet proof AM drive mechanism, it's still running great. I can even swap in a set of scale wheels for operation on a scale layout. The only electronics inside is a Dalee reverse unit for AC use and a DPDT switch to allow DC operation if desired.
Still, I can't deny that the Berk looks pretty good...
BL2's are definitely cool, but Lionel doesn't have one in O, so you won't see it in Flyer.
Let's see the Legacy Berk delivered before we start fantasizing about what Lionel's not going to make next.
