This view shows a close-up of a typical joint on the rest of the track, where the two side rails have been faced towards each other so the train rides on the rail edges. I used 14 parts for each of these joints and there are 2 per section of track. The important pieces are the 1x2/1x4 car headlight brackets which hold the track. To get the gage right I needed to add a brick height to one side and then connect them with a plate 9 studs long. Since 2x9 plates are hard to find, I used 2x8 plates and on one side I added a 2x3 plate and decorated it out with the grey inverted slope piece. Underneath the main structure you can see more 4.5V track pony-eared into the bottom of the red 2x8 plate. A red 2x6 plate is pony-eared to the other edge of the tracks. All this stuff provides more track support. On inside curves, such as the loop, the short inside 4.5V track piece is what the train rides on and the long piece is pony-eared behind for support. On outside curves such as the crest of hills, the opposite track arrangement is used. Stiff track means that the roller coaster will not loose energy quickly - every wiggle as it goes by is energy lost.
