Birthday parties with the Orange County Model Engineers (OCME) at Goathill Junction Railroad offer a unique celebration where kids and families can ride miniature trains through the scenic trails of Fairview Park in Costa Mesa. The nonprofit club operates a large-scale model railroad with miles of track winding through the park, creating a memorable outdoor experience for train-loving kids and guests.

Private birthday parties typically include a dedicated train and crew providing unlimited rides during the two-hour event, giving guests the chance to hop on and enjoy multiple trips around the railroad throughout the celebration. Parties are generally held on Saturdays in two time blocks—morning or afternoon—and reservations are required well in advance due to limited availability.

The venue provides access to picnic tables and open space for food, cake, and decorations, while families bring their own party supplies, food, and games. Parties can host up to about 40 guests, and the minimum donation to reserve the event helps support the nonprofit organization that maintains and operates the railroad.

With real rideable miniature trains, scenic park views, and a one-of-a-kind setting, OCME train parties are a memorable option for outdoor birthday celebrations that combine classic railroad fun with a relaxed picnic-style gathering.
