Abstract

Most major railways have introduced or are currently introducing computer based Maintenance Management Systems (MMS) for their Rolling Stock. Such systems are often based on either MM software for industrial applications or on commercially available data base packages. Large railway operators can justify the necessary development to adapt the software to their specific needs and their environment. Many of the private railways in Switzerland cannot afford a significant software development. The paper describes the development of a MMS in a joint venture between private railways and ENOTRAC, an engineering and consultancy company. It highlights the experience gained with the introduction and the practical use of the system. 1. Project History 1.1 Study of Needs and Feasibility, Market Survey In November 1988, ENOTRAC
