Yes and it kills that part of the ride, Speed's is there in my view to change the direction of the track or you would go into the twist to fast. Bad planning if you ask me and they needed the MCBR just to include that element. Thorpe's has no need for it, slow the coaster down another way.
Speed has 2 trains, only ran 1 and used the MCBR, so there was no need to blocl section the coaster.
Hulk, Kraken etc all near enough bring the coaster to a stop.
I am just not a fan of MCBR thats all, I just find the coasters are never the same after them.
Anyway this is going off topic a bit.
