IS ZONA is the basic tool for creation of railwey timetable (GVD) in Slovakia and the Slovak Railways (ŽSR) since the year 2000

Up to now the system works, also as a network aplication, without any major problems

Because the system architecture, its data base and user interface are based on the state developed more then 10 years ago, it calls for upgrade to corresponding modern and up-to-date level

Limits in current system The need for ongoing hardware and software maintenance

requires a modification of outdated solutions that were appropriate and the only possible at time of the system origination

The current system maintaining is becoming more complicated and difficult

In some areas it approaches the limit of technical and moral life

Integration platform Fluent transfer of final and valid train timetable data to other

IS Process of transfer must by fully automated performed on

modern and sufficiently widespread and universal platform Accordance with the agreed concept of appropriate IT

architecture which communicates with the external environment via module GRADAS (Train Timetable Database Server)

Legislation and regulations The need for upgrading the existing ZONA IS with respect

to major changes in legislation (SR, EU), which will require to extend the system with new functionalities

These includes closer links to the railway operation, shorter period of planning cycles (up to an on-line preparation of the train routes)

We can assume a need to enable external access to certain algorithms such as calculating of travel times

There may be additional candidates of ZONA IS users which extends the range of users

Main functionality demands Elimination of partial isolation of IS ZONA as the tool for

strategic planning and its full integration with the systems for operational planning of railway transport and traffic

Maintain comfort work for train-path-dealer in modern environment of MET (Manager Route Editor)

Creation of an optimal environment for adding new functionality for the following period, support of the efficient train-path sales, binding to the operational planning of rail transport

Specification of users and operators requirements

Persisting of data Relational database Oracle RDBMS Environment with the benefits arising from the simplification

of archiving and better security and data protection Operation simplification to eliminate the need of LINUX

platform. Architecture

Distributed architecture New mechanism of check-in/check-out principles Some parts of system can work off-line

Design Specification of the designer needs Migration to a modern .NET platforms The possibility of further system development and system

functionality adding using the latest development environment

Implementation and deployment of a functional prototype to verify the accuracy of the proposed architecture, functionality of the system, export data to RDBMS, functionality of internal and external communication interfaces

Training of key users The pilot operation with the support of designer Removing operating faults and claims identified

during the pilot operation Deployment of the ZONA and MET modules into

operation

Manager Train-Path Editor (MET) is used for train-path creating and editing using modern sw technology, as a module ZONA IS

MET communicates with ZONA IS bi-directionally Communication takes place through the MET and

ZONA server and is secured by encryption The application is ready for mobile users, too, who

can work abroad at meetings and after creation of the VPN tunnel to MET and ZONA server they can update and send their data over the Internet to ZONA IS and other applications

Entering the trains can be done in tabular form or graphically on the map

The application is able to display the graphical timetable sheet

Creating of a graphical timetable sheet is allowed to all users of the MET and via synchronization is transferred to other MET users

Displaying of trains in tabular form in basic and extended list

Displaying of train and its route in detailed form with all the editable parameters

Displaying of trains on the map with the possibility of route editing

Displaying of trains on graphical timetable sheet Filtered displaying of trains Creating and deleting a train Editing of train

GRADAS tool (module) allows train timetable data access and publishing which are produced as ZONE IS output

The main goal is publishing of the valid train timetable to be utilized by other related information systems

It allows to provide data on working, study, lock-out and other train timetables

The system can be made available for the needs of other users, too, especially other users or the general public (passengers)

Data on trains (common and standard data on trains, train route)

Data on calendars and services

Data on infrastructure (locomotives, transport points, route segments, track units)

Classifiers (fixed or completed by users, used in other structures)
