TrainDy is a UIC-approved software program that calculates longitudinal forces along trains. A key feature of TrainDy software is its capacity to solve both pneumatic problems (venting of brake pipe and filling of brake cylinders) and mechanical problems (computation of relative movement between consecutive wagons). This feature makes TrainDy particularly useful for studying new freight trainset compositions. TrainDy can be used to:
TrainDy software is managed and developed in Matlab (international standard programming language) by the UIC TrainDy Special Group.
Operators/Industry: Faiveley Transport (a Wabtec Company), Knorr Bremse SfS mbH
Research Institutes: RAILENIUM, TUBITAK RUTE
Universities: University of Rome Tor Vergata, Technical University of Berlin, University Antonio de Nebrijia
UIC-Members:
Objectives The objectives of the special group are to keep the TrainDy software up to date and to increase its membership in order to maximise use of TrainDy among freight operators and deliver services to customers interested in productivity gains.
The following possibilities of development have been analysed in the TrainDy+ final document:
The results of the Project 706 are available on UIC ETF shop:
IRS 40421 allows train compositions exceeding the length/mass limits if longitudinal forces are assessed with multibody dynamic software such as TrainDy, and describes a statistical method for generation of random trains in accordance with technical and operational parameters such as wagon type, train mass (or length), wagon payload, etc. However, TrainDy did not have a tool to generate random trains taking into account varying technical parameters. to overcome this a statistical tool was developed by the University of Rome Tor Vergata and has been validated by the TrainDy Special Group.
IRS 40421 content is also the result of the study for the CEF-PSA UBS action project. The study has been carried out by SNCF as member of the Special Group TrainDy. The results of the Project 496 and the report of the study for the CEF-PSA UBS action project are available on UIC ETF shop:
The results of the Project 573 are available on UIC ETF shop:
The basic principle of Long Train project have been further developed by TrainDy members in the framework of the projects FR8RAIL II and Marathon2Operation, a Shift2Rail project coordinated by the University of Rome Tor Vergata.
