Designing a new monorail suspension system for an existing monorail bogie to accommodate larger cars, locomotives and more passengers is a complicated and challenging problem to solve. In this paper, a model of 15 degrees of freedom full-car Monorail suspension system model is proposed. In this paper, simulation is performed to predict some dynamic characteristics monorail suspension system. The model features the Monorail body, Front bogie, and rear bogie geometries, adopted equations of motion of the monorail body. Numerical Central Difference method was used to obtain the system responses subject to sinusoidal Track excitations. Different driving speeds of 36, 54 and 72 $km/h$ were simulated to investigate the train’s vertical, lateral, roll pitch and yaw displacements. Results, included monorail body displacements in terms of vertical, lateral, roll, pitch and yaw displacements. It was found that Monorail body displacemnets ere inversely poroprtional to driving sppeds within a range of 0.31mm nad 2.5mm. Also, roll, pitch and yaw displacements were small within a range of 0.75 to2mm.
