I ordered my 5415 earlier today, February 8, 2019. The email from Mr. Muffins said they had 22 pre-orders. Mine would make another at 23 or more. It should be a beautiful engine. For all the trains in my collection, the only Hudsons are the Empire State Express #5426 and #5429 with plated tenders that pull my two sets of 21" NYC ESE passenger cars.
It will be good to have steam engines for pulling freight; this #5415 and the #5416 Hudson are pre-ordered. It will be a busy Christmas season with their arrivals.
Sincerely, John Rowlen
