SYNOPSIS The paper describes the present acoustic environment in railway passenger vehicles, and discusses the various mechanisms leading to this. The factors providing a basis for an internal noise criterion are stated, and suitable criteria for different classes of stock suggested. A more detailed discussion is presented of various problems encountered during investigation, and of the experiments and analytical techniques evolved during their solution. It is pointed out where the experience gained in this work can be applied, and also where gaps still remain to be filled by future investigation.

Accident Statistics

The loading specifications to which passenger vehicle body structures are designed seek to fulfil two basic requirements. Firstly, normal service loads experienced over the life of the vehicle must be met without loss of serviceability. Secondly, passengers and crew must be afforded protection against loads outside the normal service experience. In the specifications used in Europe and the United States there is an emphasis on ‘proof’ loading, that is loading which causes no permanent deformation. This requirement is in conflict with the absorption of energy which is necessary to cushion passengers and crew involved in an accident. The author examines UK accident statistics and proposes alternative ways in which the basic aims of structural crashworthiness can be met.

This paper describes a concurrent design approach to railway vehicle design. Current railway vehicles use many different concepts that are combined into the final design concept. The design support for such systems is based on reusing components from previous design cases. The key part of the railway vehicle design concept is its simulation model. Therefore the support is based on support for reuse of previous simulation models. The simulation models of different railway component concepts are stored using the methodology from the EU CLOCKWORK project. The new concept usually combines stored components.

Railway Passenger

The most important element in railway passenger transport is a customer – traveller, who requires the transport from one place to another. A basic precondition for accomplishing the main requirement – transport, is making the complete offer which provides not only transport, but also other associated services. Practically, there are many associated criteria of transport, for example safety, duration, price, reliability, comfort and complementary services. Passenger transport is generally considered as an activity, which arises as the consequence of spatial division of places, where people are in exact time and their need to move. Motivators for moving could be commuting – job or education, dealing with personal or working matters, travelling for vacation – hiking, sport, health, cultural and social facilities, visiting relatives and friends. Requirements for transport of passengers originate in the need to move, while the passenger transport is dependent on the willingness of travelling. In passenger transport, there are mostly individual passengers, so it is difficult to determine all transport requirements. The paper is focused on one of the key factors of passenger transportation - connectivity of trains. Connectivity of passenger trains and other means of transport can be distinguished also from temporal and spatial point of view. Temporal connectivity is such sequence of arrivals and departures of different passenger trains and other means of transport, which allows changing the different passenger vehicles easily in regard to necessary time. Spatial connectivity means the distance between two passenger vehicles, among which the passenger is moving. In the paper, there is described the general methodology for calculation of minimum transfer time in the railway station. Railway passenger station is some kind of transport hub – a starting and finishing point for flows of passengers. Passengers have the opportunity to change the train type from long-haul train to regional train or contrariwise or simply enter or leave the system of railway transport. In the methodology, all necessary aspects are taken into account.

The Many

A method is presented for the concept design of railway passenger vehicles. The method requires adequate mathematical modelling for describing quantitatively the many relationships between vehicle parameters and vehicle performance indexes. The main purpose of the method is defining the layout of vehicles (i.e. length, number of wheelsets, etc.) in order to obtain the lowest possible life cycle cost (LCC). The method is based on multiobjective programming (MOP), a branch of operations research. By the proposed method, the optimal design of railway passenger vehicles can be performed in a theoretically correct and rigorous way. Genetic algorithms (GAs) are used to find the numerical solution to the problem. The optimal design of urban, suburban and intercity (IC) passenger vehicles is performed in order to obtain the best compromise between conflicting requirements such as maximum payload, minimum tare weight and axle load, minimum track deterioration, maximum ride comfort, etc. It is shown that, with respect to modern vehicles, a major improvement in LCC would be gained if shorter vehicles and newly designed wheelsets and/or bogies could be adopted. Should this happen, new families of passenger vehicles with two or three axles would be the optimal solutions to be built.
