Have not seen this particular set before, but is the box a single tier or double tier? Are there any cardboard inserts present? If a double tier box, there is the possibility of extras such as a Lionel boxed Plasticville kit or extra track (90 degree crossover).
Since the 202 is an entry level offering, rolling stock could include a 6014, 6017, 6025, 6111, 6112, 6121, or a 6476.
Good luck and have fun in your search...
