The answer is not so simple . . . . .
If a product has doubled in value on the secondary market, by definition, there is great demand. Why does Lionel not reissue:
1) Legacy sound tank cars
2) Die cast ES44AC locos
3) EVO GE
4) Milwaukee S-3
All of the above have proven that on the secondary market people are paying much more than the original price.
Lionel has been unable to predict accurately enough what the public will or won't buy.
The lead time, currency fluctuations, manufacturing backlogs, and failure to deliver in a timely manner has shaken the production chain to the point where they are unsure what, how, when, and for whom.
I remember talking to three or four "marketing" reps at York all of whom were younger than my son. I explained I would not buy the new steamers without whistle steam. They said it was too expensive, too big for the bodies, etc. etc. I asked why they would put it in, show the market how cool products could be at a certain price point, and then take it out and leave the product at the same price point. They said that the locos were not shabazz shabang without unglook and turpentine. I said, "Whaaaaaaaa?" What are you saying ? Ummmmm, I couldn't figure it out.
The proof is now they are making the number to order.
