Comes complete as shown in my pictures. I know it works - it was tested before it was taken apart. 19 straight track. 28 curved track. 5 switch tracks that have wire attached. 2 tracks with the plastic crossover plate installed. (Not 100% sure what that’s called). 9 rail cars with one caboose. 2 engines. Parts to make a bridge or railroad trestle? Control box with power cord. Extra wire and a film container with various parts and pieces. Some instructions included. Please see all of my pictures and let me know if you have any questions. Thanks.
