Functionality
- The regular interval train concept provides an efficient way of editing all trains within the same family
- Any level of detail is in the modelling of the train path (down to the signal level)
- Used track in stations as well as additional running and stopping times is possible as input
- Calendar based definition of validity and operating days

A train timetable goes through many different planning stages over its long period of development. The process starts with a draft long-range service plan, which is constantly refined until it is used to operate the trains and then, finally, to analyze system performance. Finding the timetable that best balances the railway’s operational and economic needs requires much iteration. |

 The choice of database for Viriato depends on the number of users and amount of data. For stand-alone workstations and small work groups, Viriato uses a standard MS Access database. This provides good performance, flexibility and simple administration.
For larger work groups with numerous concurrent users and large data sets, it is possible to use Viriato with an Oracle or SQL Server database. These databases offer better performance, security and availability than MS Access and provide administrators with data management tools. |

 Customer Timetables are traditionally used by railways to provide customers with information on train arrivals and departures. These timetables appear in timetable books and are frequently found hanging in stations and at stops. While customer timetables are simple and clear representations of a timetable, they are not easily understandable for everyone. However, timetable comprehension can be significantly improved through the use of good design, graphics, typography and color. |

 Time/space diagrams, known in the railway industry as graphic timetables or train diagrams, have traditionally been used to represent train operations. They are the central working documents for timetable planners.
An experienced timetable planner can assess the feasibility of a proposed timetable and can immediately recognize problems, such as insufficient headways or conflicts on single track sections, simply by looking at the graphic timetable. Graphic timetables can also be used to develop draft plans and estimates for vehicle use. |

 The introduction of coordinated nationwide timetables created the need to present time/space relationships not only on particular line segments but also on a network-wide basis and it marked the birth of the “netgraph”. This representation, when supplemented by other information such as timetables, duty schedules, and track occupancy plans, is suitable for internal railway purposes. All these documents reflect the onward or circulating progress of trains and are based on a finite amount of common data. |
