Update on the models of 90:
Ryan announced last night on his "Workbench Wednesday" live stream that Lionel is expecting engineering samples of 90 end of Dec./early Jan. - he relayed that he told the factory to take their time and make sure it's right. He also said that he approved SRC passenger car deco (painted?) samples recently - I am hoping they will be exact color match to MTH versions. Sounds like good news all around regarding both items.
