The past decade has illustrated that the Signature catalogs are mostly the scale proportioned products, and this was no exception. So my time comes when the next Ready-To-Run catalog comes out next year.
For a company most recognized for TOY trains, Lionel has made great strides in the past 15 years on the scale end of the hobby. And considering that in Lionel's own words, that a single locomotive run of 3,000 units is an exceptionally large run for a single scale product, Lionel is going to great effort to "try" and please the scale side of the market... also considering that 3,000 units is a small run for a starter set.
Actually, I do understand this marketing move: In the traditional market, Lionel is competing with the entire past production on the secondary market (of which production numbers are substantial), but also K-Line, RMT, Industrial Rail, Williams, MTH Railing, Kusan/AMT, MARX, Menards and others.
The scale market is the new thing and although there is competition here too, the production runs are much smaller. Atlas, MTH and Weaver were operating on a BTO method long before Lionel openly started the same procedure.
Some have already expressed reservations though, wanting to see if these products will meet their expectations. Yet, most of the products in this catalog are under the BTO banner. So, unless folks are willing to take a chance and commit to making a purchase, the product may get cancelled.
I'm certain, as others have expressed, that the SD60's - especially in the various Norfolk Southern schemes are going to be popular (I'd love to see one of those paint schemes on a traditionally sized product however un-prototypical).
But unless folks pre-order, they're going to be left to the dealers who take a calculated risk and order extras. And I think the larger dealers who are doing this, are quickly going to figure out just how many extras they can safely order without being burned themselves since BTO moves the risk factor from Lionel itself and onto the distributors and dealers.
