Six Flags Great Adventure opened in 1974 and one of the park's original attractions was the Skyride which runs from the iconic Fort Structure to the Dream Street station high above the treetops of the theme park originally known as "The Enchanted Forest". It is the last remaining dual Von Roll Skyride in the world, and the components of the ride were recycled from the 1964-65 New York World's Fair (as seen above) and the defunct Freedomland park in the Bronx, NY. The mechanical parts of the stations along with the original fleet of cabins came from the World's Fair, while the towers came from Freedomland. Both rides were purchased by a developer and were supposed to be relocated to Canada in the late 1960's but were held up in customs in Upstate New York. Those parts were then purchased by the developers of Great Adventure and reassembled by Von Roll. The Fort station is the tension station with the counterweights hanging beneath the station floor. Those counterweights maintain the proper tension on the cables as the weight changes as gondolas load and unload. The weights are steel plates (seen below) which pull cables on the bull wheels that slide on tracks to adjust the tension. That movement is monitored with the rulers attached to the anchorings.
When Great Adventure opened and into the early 1990's the gondolas used on the Skyride were the fleet from the Swiss Skyride from the 1964-65 New York World's Fair. Those cars were retired from service with two remaining as maintenance cars which have the roofs removed so the maintenance team can service the rollers. The remaining cars were given away or sold. One of those cars ended up in a playground and was eventually sold on eBay where I acquired it. With no time to devote to doing the restoration work needed on the gondola it was sold to another collector of World's Fair artifacts who is in the process of restoring it to its former glory. The gondolas currently in service at Great Adventure came from Six Flags Great America in Gurnee Illinois. That park was home to two skyrides and when they were removed the fleet of 84 gondolas was sent to other parks with skyrides. Initially they were painted red and blue, but since sponsorship by M&Ms began in 2011 they were repainted in the colors of M&M candies and feature the distinctive "M" on them.

The Dream Street station features the name "Skyway" on it, and is the power station where the electric drive motors turn the bull wheels to propel the cable. The station is also equipped with backup motors for each of the cables as well. Originally they both had Volkswagen engines which were ideal for the purpose being simple to maintain and air cooled. More recently those were updated with larger motors which feature radiators. It appears from the yellow coloring on the fuel tanks that the new motors are diesel powered.  The Dream Street station is also the primary storage for gondolas, with each side featuring three storage tracks for the fleet of cabins to be parked at night. The maintenance cars are also kept in the Dream Street station where there's a maintenance shed, along with any cabins being serviced.
