Get yourself a copy of
Roller Coasters, Flumes, and Flying Saucers by Robert Reynolds. The book is $20 from Northern Lights Publishing, and it details some of what went into building that ride. For a look at the mechanicals, take a look at US Patent #3,114,332 which you can view in its original form at
http://www.uspto.gov or you can visit
http://capital2.capital.edu/admin-staff/dalthoff/bobsled.html and see my HTML rendering of it.
I've never ridden the thing myself (I was four years old the last time I was at Disneyland) but
Guide To Ride 2000 says it is 80 feet tall, has two 2,134 foot long tracks, and runs twenty 2-car trains.
