Transport systems revolve around their schedules. Computer scheduling systems are now installed in very many transport organisations, and savings are well documented. These may be: direct savings from more efficient schedules; indirect savings because of the ability provided to investigate speedily alternative scenarios; induced savings where the computer has pointed out how adjustments to timetables or operating rules would increase efficiency. However, the use of an IT system for scheduling does not, in itself, guarantee a good schedule. There are many attractively presented systems that produce poor schedules, often quite quickly. These should be avoided, and it is important that people involved in the choice of systems should appreciate the distinction between good and bad algorithms. We report from our own experience on successful uses of IT for scheduling and show some of the pitfalls.

This paper outlines an overall CNS/ATM architecture, its components flow between (common functional architecture) and functional blocks allocation to the organisational units (system architecture). It does not represent the final architecture but defines the technical framework for the harmonisation and integration efforts. It is the baseline for the specification work for implementation in 2001-2005 in the framework of the EATCHIP Work Programme, serves as an information source for local planning actions by the national administration, serves, at a lower level of decomposition, as a framework for detailed architecture work, and is a baseline for the SATMS development.

Modernisation of railway transport is not possible without complex modernisation of railway stations and junctions. This modernisation will actually mean their preparation for implementation of the main tasks of railway for the future. The paper presents some of the most necessary arrangements, without which the railway will not be able to compete with other modes of transport.
