A rapid transit system with wheel in track design includes a guideway, a vehicle that includes a vehicle bogie or chassis that couples to the guideway, and one or more terminals and/or intermediate stations. The guideway may include a first guideway and a second guideway, with a switch guideway interposed thereinbetween that allows the vehicle to move from the first guideway to the second guideway or vice versa. The vehicle may be coupled to the guideway via the vehicle bogie. The bogie may have a first axle, a second axle, and a third axle. First and second sets of guidewheels propel the vehicle forward or backward. The first set of switch wheels and/or the second set of switch wheels may be engaged and interact with one or more first or second neutral rails or first and second switch rails to move the vehicle from guideway to guideway.

A track beam includes a main component and a guide component. The main component includes a top plate, a bottom plate, and a web plate. The bottom plate is disposed below the top plate, and the web plate is connected between the top plate and the bottom plate. The guide component includes a guide plate and a connecting structure. The guide plate is disposed between the top plate and the bottom plate. The guide plate includes a planar plate structure extending in a longitudinal direction and is spaced apart from the web plate in a transverse direction. The connecting structure is connected between the main component and the guide plate such that the guide plate is connected to the main component through the connecting structure.
