The train going in the intrincate curves of the roller coaster imposes significant dynamical forces to such construction. Hence, modernly a roller coaster would be preferably designed by one with significant knowledge on structural dynamics, which falls a bit off-center of most architects, and more centered in some mechanical, civil and aircraft engineers.
A traditional approach (now being discarded due to the availability of better analysis and design programs) is to use significant amounts of bracing to keep key points firmly braced unto a fixed position, and then tie the rails and other minor structural elements to such "mega"-structure. In modern design you still will see the bracing but not likely so densely througout as in older roller coasters.
