Here's an update showing off some of the rehab going into various coasters this season...
Loch Ness Monster
Busch Garden's Park President has confirmed that Nessie will indeed be getting updated trains for the ride's 40th anniversary. While I believe that the chassis of the train has been reused and rebuilt, everything above is new. The train bodies, and headrests have been reshaped and resemble Arrow's later train models. Parts of the track are also being repainted to commemorate the historic ride's tenure.
Six Flags New England- "The Riddler"
Mind Eraser is currently being transformed into The Riddler. The red and teal paint scheme is turning into green and yellow, similar to that of Six Flags Magic Mountain's Riddler's Revenge coaster. Along with the new name and paint, I believe that the ride will also receive second generation SLC trains from Vekoma, like those found on Morey's Nor'easter.
Canada's Wonderland- Vortex
Along with the construction of their 2019 roller coaster, it seems like Canada's Wonderland is already getting a head start on the surrounding area refurbishment. Vortex's trains have gotten a cool new paint scheme, and is rumored to be getting a "timber" themed name as well.
Sources are unconfirmed, but by next season, the track may be getting a full paint job too.
It has been known for a little while that Canada's Wonderland has stated future plans containing a new roller coaster and a hotel. According to planning documents filed at a planning meeting last week, the construction period of the ride will be from January 12th 2018 to January 11th 2020.
This means that the roller coaster will likely be open for the 2019 or 2020 season. The ride's specs and model are not specified, but all we know is that it will be placed somewhere between Vortex and Windseeker. One of the features of the ride will be a tunnel which dives into the pond, like Anaconda at Kings Dominion does.
This is not too large of an area, so I would assume that Cedar Fair may be looking at more of a compact model, such as a Dive Coaster, or similar type of ride. The big gimmick will be the dive into the water.
As for other news, there are plans in place to update the park's entrance and parking plaza, which could be completed by 2019. Cedar Fair has never been fond of the old Paramount Parks' infrastructure, especially on the front end. Look for them to do some work here, and parks like California's Great America in the future.
The hotel will likely open by the 2020 or 2021 seasons, but I have yet to hear solid sources on this one. No planning documents have been filed, but Cedar Fair is looking to design and brand this hotel as their own, much like they do with Breakers at Cedar Point. Carowinds has been subject to similar rumors, being one of the flagship parks.
Canada's Wonderland decided to use a smart technique for the 2017 season. Add one attraction to the water park, and one to the dry side. Both of these attractions should be relatively cheap, and will bolster the lineup for both sides of the park.
Muskoka Plunge will be a 60 ft tall set of 4 drop pod slides. This slide complex is probably the same one that is going into Cedar Point and Knott's, but that really isn't an issue here. Unlike copying flat rides, water slides tend to be pretty standard. Whereas someone may only like a few Boomerangs or SLCs, water slides are a lot more popular altogether. I am a firm believer that every water park should look into investing in a drop pod slide. It is unknown whether or not this slide complex will also have the dueling tube slides like the others do.
Soaring Timbers is the addition to the dry side of the park. Keeping in tradition with adding unique flat rides to the park, Soaring Timbers will be the first of its type in North America. Also, considering the relationship that the park has with Mondial, this attraction will be built by them. It is one of their "Inferno" models. Riders board two 19 person gondolas, and swing around a 45 degree arc with swinging and flipping seats. It is truly something that I would be excited for if I were a Wonderland frequent.
Reason: This isn't the first time that a park has done the "One Wet, One Wild!" slogan. It works very well whenever a park does it, and these attractions are great for the park. Thrill riders should be very impressed with these. The reason for the high grade is because it was not expected, and serves Wonderland well. This is a dark horse for best new addition next year for a Cedar Fair park (besides Mystic Timbers)
