The answer is yes. Lionel and Atlas O scale trains are 100 percent compatible. You differentiate model and toy trains according to their scale and their gauge. "Scale" relates to the comparative ratio of measurements between the model and its full-size counterpart or prototype.
"Gauge" the second aspect of a model's size, refers tp tje space betweem tje rails of the track, For O gauge this measurement is 1 1/4 inches. These same models are built to a ratio of 1:48 so a 50 foot long real (prototype) locomotive would be 12 1/2 inches in length on the model.
Atlas model trains will run on Lionel track and vise-a-versa. The two companies also use the same style and type of coupler along with the same hieight for holding their trains together. I hope this helps and if you need more information e-mail or call me, thanks.
