It is one of Lionel's latest batch of EM-1s cataloged in the 2019 v2. The product number for this particular model is 2031110 and has the MSRP of $1700. I am currently trying to get a product review done on it and I will post it here on the forum under "What Did You Do on Your Layout Today."
Thanks TM; love that whistle; I have the 2031090 and, so far, runs great!!
