The park was served by the Boston, Revere Beach and Lynn Railroad, known as the "Narrow Gauge".
Today, the rail stop is named Wonderland and is the northern terminus of the MBTA's Blue Line.
Largely because of the nationwide economic downturn known as the Panic of 1907, Wonderland was bankrupt at the end of the 1908 season.
The Park managed to continue operating until the end of the 1910 season, then closed for good.
This is probably because the site was originally a marsh, and the Wonderland Park builders drove 60,000 spruce pilings into the ground to give the buildings a firm foundation.
