It looks like the sort of coaster that should be defunct and only seen in a black and white photographs. Surprised it's still operating.
the twin/mobius-tracked wooden racing coaster is an interesting specimen.
they were quite popular back in the golden age, with about 3 dozen of them built in the pre-war era, primarily in north america, with only two surviving examples: Kennywood's Racer and BPB's Grand National.
then in 1972, KI's Racer kind of kicked off a little mini-resurgence of the style over the next decade+ with 6 more examples being built at parks across north america, La Ronde's Monstre being the last, and one of the largest, of that wave.
there was also another little mini-resurgence of them in the late '90s with another 4 built, but since 2000 only two have more been built globally: Joris en de Draak at Efteling in 2010 and Dauling Dragon in China in 2012.
and of the 13 post-Racer twin tracked wooden roller coasters in the world, 5 have already been lost (3 for RMC conversion and 2 others simply removed).
building one of them kinda seems like a somewhat bad investment to me. yeah, you end up with a pretty high capacity ride, and the whole racing/dueling aspect can add an extra element of fun to the experience when operated properly, but you essentially double the expensive man hours required to properly maintain wooden coaster track over the lifetime of the ride. I'm a little surprised that we didn't see more examples like CP's Gemini that went fairly far to sorta mimic the whole experience, but used lower-maintenance steel tubular track instead.
as for La Ronde's Monstre, it will be interesting to see what happens with it long term. I know I've heard (wishful) rumors over the years of possible RMC conversion ala Twisted Colossus or Iron Gwazi, but do they have the resources for that kind of serious investment?
