Any time you have a question on shipping dates, go to Lionel’s website, click on “support” and then “shipping schedule.”
It’s not the most convenient list since everything is listed chronologically by expected shipping date and the text isn’t searchable, but that’s where our information comes from.
Also, it isn’t updated very frequently, so if you have a question on a particular item, check with the dealer you ordered from as the shipping date estimate draws close. Distributors often have updated information at that point.
