One ride I would like to be included, like it was in RCT3, is the Side Friction Coaster. This particular wooden coaster only has a one slope incline and the same for downward slopes. This is a very old coaster design, that was often known as a Scenic Railway. There are still a few still in operation in the UK and if I remember right, John (Zak) mentioned the one at Great Yarmouth. These coasters can also make a good transport ride, by placing multiple stations at various points in your park, but like the Miniature Railway it has to be a continuous loop, because it can't operate in shuttle mode. So you can't build it like the Monorail where you just have two stations at each end of the park, operating in the shuttle mode.
I really liked this coaster in RCT3, because they were never seen to be built high, more of a gentle flowing ride, and good for building Junior Wooden Coasters.
