LEGO 6399 Airport Shuttle Town Monorail

LEGO 6399 Airport Shuttle is a Town Monorail set released in 1990, containing 767 pieces and 9 minifigures. The set builds a red two-car monorail with a centrally mounted 9V motor and a battery box housed in one car labeled “Airport Shuttle.” Included figures represent airport staff—a train conductor, pilot, baggage porter, cook, and an airport employee—alongside four passengers. The train runs on an elevated monorail track system, and LEGO also offered 6347 Monorail Accessory Track the same year, which introduced the first monorail switch tracks.

The current value for a new and sealed Airport Shuttle is estimated at $4,352, with an average annual growth of approximately 6%, which is lower than other Monorail sets. On the open market, a used set will sell in the range of $910 and $1,188, depending on its condition.
