Role of the consultant in mass transit systems

Abstract

The main theme of the paper is the very wide range of disciplines involved in the design of a new mass transit system. The paper deals with the role of the consultant rather than discussing particular solutions to technical problems. The importance of co-ordination of all electrical and mechanical engineering both within their systems and with the civil engineering and architectural design is explained and stressed. After outlining the methods of route location used on early systems, the current way of assessing the potential number of passengers along the corridors is described. Factors determining the train size are outlined and the many requirements to be taken into account in designing the train identified. Particular mention is made of electrical aspects and some technical details, particularly those relating to power supply, are given. Emphasis is given to other matters in the domain of the electrical engineer, such as signalling, train control, telecommunications, fare collection and the environmental control system. Industrial and graphic design work by consultants is covered in addition to the architectural aspects. The wide role of the consultant in the fields of financing, organisation and operation of the system are touched upon to show the diversity of professional expertise involved.
