Hello. I believe you are looking for the #1050 New Englander set. It came with a 2-6-4 steam engine, DC powered, I believe. Lionel engine model# is 8007.
Just as a follow up,the other cars in the set were a #9035 blue Conrail boxcar,a #9036 white Mobilgas tank car, and a #9140 green Burlington gondola. I hope this helps. "Impala"
