Timetable design and construction; Complete train patterns for entire days are easily created with the
Timetable Manager. The train routes are interactively specified within a network graph. Automatic
calculation and evaluation of running times, block occupation and resolution of conflicts with other
trains network-wide is provided as soon as a train is entered or edited.
Assessment of the operational quality; Does the timetable work in theory No day is like another one
in real life. Small and large perturbations cause delays. The Simulation Manager simulates a variety of
operational days with realistic and individual delay characteristics. The Evaluation Manager supports
the assessment of the simulation results. Various statistics provide dependable information about
delays, resulting punctuality, or the quality of connections within the network, lines or stations.
Infrastructure planning: The Infrastructure Manager is designed for accurately capturing, editing and
managing of all infrastructures of any size. Infrastructure can be entered as a draft. The comfortable
editing functions allow easy updating. Changing of infrastructure designs are captured in multiple
variants. The variants are used for timetable construction, possession planning, simulation and
operational comparison of different planning stages with the Timetable and Simulation Manager.
Operational planning for track work: Building new or maintaining existing infrastructure often causes
deteriorated conditions for train operation. The Timetable Manager evaluates and precisely locates the
resulting conflicts. The user can interactively alter the train schedule in accordance with the track work,
or reroute trains within the network. Any time penalties as well as the remaining train path options are
displayed in tabular or graphical form for trouble-free operations planning during track work.
Optimisation of train operations due to track possessions in terms of blockage or downtime can be
planned by using two RailSys modules “Possession planning” and “Alternative tracks” – giving the
information of alternative paths in case of track blocking or downtime.
3.2 Possession planning by software RailSys
There is an increasingly common need for performing maintenance and/or retrofitting and installing
extensions 'on the fly', that is, during ongoing operations. The costs for alternative transportation or
downtimes must be kept at an absolute minimum. The purpose of possession planning is to determine
how to best ensure a timetable free of conflicts. Questions such as "When will trains be running
according to schedule again if a switch is down for several hours", or "Is it worth implementing
additional infrastructure, because in the case of a locomotive failure the remaining traffic cannot flow
smoothly", can be answered by putting in the rail sections that will be blocked for a specific period
into the RailSys software. [1]
We can create:
- speed restriction or
- track blocking.
