78 Glendale St. in Dorchester seems like just the place for a large family, with seven bedrooms and three bathrooms. And one Red Line room. Scroll through the interior photos at that link. Keep scrolling. It'll hit you: A wall-size mural of a Red Line train, only one that then extends into the hallway with a door that lets you enter a "train" room that looks like what you'd get if you turned a Red Line car into a room (only with a giant circled F instead of a T).
