FWIW, many of the previous BTO items are available at various shops now, the dealers typically order extras.
And at good discounts too. The Legacy ESE hudsons can be had for $1099 at Charles Ro.
Good thing I preordered.....never again.
Given that many times a Lionel loco can be noticiably "different" for the catalog and/or prototype in one way or another, i.e. sound ,features, color, etc.
I highly recommend NOT preordering and wait until the product arrives and is reviewed here by another forum member.
That way, you know exactly what you are, or aren't getting before you buy, along with any potential operational issues.
Charles Ro and Trainworld to name a few, always have extras for several weeks to several months after delivery.
