<p align="justify">Kereta Kapsul as a mass transport vehicle which is expected to be one of alternative solutions to cope with congestion in urban areas. One of the scope of the design of Kereta Kapsul processes is the analysis of the needs of the drivetrain and the braking system. The drivetrain relies on traction motors without a transmission system. The output shaft of the traction motor is coupled directly to the wheelset using the falk gear coupling. This final assignment is structured to estimate the power and torque requirements of the driving force and the loads that the braking system must bear. <br /> <br /> The calculation of driving loads is performed by using a quasi-static method of d'Alembert principle based on initial design criteria. Calculation criteria consists of several conditions that must be met and some conditions that expected to be met. <br /> <br /> Based on the calculations, the requirement of the propulsion of the Kereta Kapsul with the maximum acceleration of 4 km/h/s can be gained by using a traction motor that can exerts of 109,31 kW of power output. The torque output of the traction motor is 1,01 kNm for each motor used in order to achieve the maximum acceleration without any slip occured. <br /> <br /> The calculation result of the braking system requirement is the force which is required to slow the vehicle in an emergency condition of 4,5 km/h/s is 9,53 kN whose value is under the skidding criterion, which is 10,54 kN. To produce the desired deceleration, the requirement of braking torque is 2,95 kNm for each wheelset. Based on the calculations of emergency braking force compared to the skidding criterion, the vehicle will not skid while the braking torque applied by the braking system. <p align="justify"> <br />
