Specialized Software has been developed and designed for planning, control and maintenance of transportation systems to prevent breakdown and ensure customer safety and satisfaction. Trains are at risk of facing mechanical problems that can lead to accidents and service interruptions if maintenance has not been properly observed. Thus, the researchers conducted the study which aims to develop a computer based maintenance system (CBMS)  that will provide (1) more accurate preventive maintenance (PM) schedule (2) easy monitoring of available technicians to handle the maintenance and (3) spare parts monitoring to ensure that the items are available when needed. This research presents the design of an application software covering scheduled preventive maintenance for rolling stocks, preparation of ticket request for corrective maintenance, notification of assigned technicians, recording of spare parts to be used and generation of reports relevant to user’s/ manager’s decision making functions. The authors were able to assess the current maintenance and scheduling processes to determine system requirements and come up with the design that will improve the maintenance system.
