QUOTE: Originally posted by cuyama The helix is relatively compact in footprint, but adds a substantial grade, which is usually hidden. This long hidden run is the reason many people look for alternatives.
QUOTE: The around-the-room-helix allows the track to climb as it circles around the room, eventually reaching a new elevation. This takes a lot of room, in a sense, because it often wraps around the whole space, but you can see the train the whole way and it's possible to add passing sidings or towns along the way in some cases.
