The Fisher-Price Little People Express Train #2581 took the beloved elements of the long-running #991 Circus Train and gave them a fresh spin for a new adventure. Featuring a modified engine, flat car, and caboose, the set comes with four Little People figures -including an engineer, mom, dad, and a dog - plus two vehicles and two pieces of luggage for imaginative journeys. While most pieces were adapted from previous sets, the two vehicles included were exclusive to the #2581 and are now considered somewhat hard-to-find, especially after being omitted in 1990. Compact yet detailed, the Express Train combines classic Little People charm with interactive play, making it a favorite among collectors and fans of vintage train sets.
