Abstract
In order to increase the productivity of freight trains and to harmonize the
standards of different countries, there is the need for a new and reliable
numerical simulator, since the in-line test campaigns are expensive and they
should be reduced to a minimum amount. Furthermore, this simulator should
easily be customized by each Railway Operator. In order to face these
challenges, the UIC decided to improve and to validate the software TrainDy,
and to deliver its source code to railway Operators, Research Centres and
Universities that will join an ad hoc Consortium, led by the UIC. This paper
gives the outlines of the numerical models implemented in TrainDy and shows
some of the results of the validation process undertaken.
Keywords: longitudinal forces, improving freight trains productivity, modelling
of pneumatic braking.
1 Introduction
Longitudinal forces (LF) exchanged by two consecutive vehicles of a train have
a great impact on suitable length, applicable traction power, capacity and
permissible speed of freight trains. Wrong decisions concerning these parameters
result in accidents due to derailments, damage of wagons, goods and railways,
but also in higher maintenance costs and lowered capacity. In order to increase
freight train productivity, the International Union of Railways (UIC) has
provided software for the calculation of LF for more than 25 years to the
participating railways. Now the UIC has decided to develop a new system and to
