Falko OnlineTimetable management for the Vicos system

Falko Online is a variant of Falko and used in connection with the Vicos OC 500

control system. Falko Online features two central functions:

Dispatching of the current Vicos timetableIf a fault is encountered in current oper-ation of the Vicos system or if the time-table which is active in Vicos is to be modified for other reasons, this currentVicos timetable can be edited using FalkoOnline in order to minimise the effects of the fault.

For this purpose, the current Vicos time-table is edited and validated using FalkoOnline. After editing, the edited time-table is sent to Vicos where it can be im-plemented.

Operational planning is the major stepfor Falko for dispatching the current timetable since its strategies permit simple and rapid modification of the timetable.

Timetable management for VicosFalko Online manages timetables for theVicos system. To this effect, it functionsas the interface between a “normal” Falkosystem and the Vicos operations controlsystem.

The timetables are designed and valida-ted using Falko. After exporting, they areautomatically passed on to Falko Online.

If the versions in Falko Online are moreup-to-date than those in Vicos, the rele-vant files are sent to Vicos. Timetablemanagement and interaction with FalkoOffline and Vicos are fully automatic andindependent of user input.

System requirementsThe same system requirements apply forFalko Online as for Falko Offline. In addi-tion, Siemens supplies the Vicos NetworkCoupling Unit program which imple-ments interaction between Falko Onlineand the Vicos system.

Performance features> Modification, input and deletion of

vehicle runs> Notepad approach combined with

scripting language> Easy-to-operate user management> Re-use of existing offline functions

(e.g. simulation)

Range of functions> Falko Online is used for dispatching

existing timetables which already exist as vehicle schedules.

> The current list of scenarios which Falko Online manages for the Vicos system can be output, showing not only the scenario name but also the version number and the correspondingVicos name of the relevant timetable.

> Additional shortcuts enable rapid access to the functions frequently usedduring dispatching.

> The user interface of Falko Online is similar in design to that of Falko Offline.

Falko Timetable DesignConvenient handling – timetable design in easy steps

Timetable design is performed using the combined representation of the track layout

and a symbolic timetable. First of all, the symbolic timetable is specified and then an

operative timetable is generated.

Timetable generation

Expanding the timetableThe first step in the generation of anoperative (actual) timetable is timetableexpansion. Here, the specified symbolictimetable is expanded into individualtrips.

Generating the vehicle scheduleIn multi-depot vehicle scheduling, indi-vidual vehicles are assigned to varioustrips. The objective is to minimize the resources used.

Performing operational planningIn operational planning, the vehicle schedule is refined down to the level ofstation tracks, taking account of reversaland stopping as well as pull-in and pull-out strategies.

RoutingThe routing function creates an opera-tive timetable from the running orders. It takes all relevant route exclusions intoaccount.

Timetable specification

Defining and linking linesIn the track layout display, the lines areentered with the stopping points. The lines can be combined serially (followingeach other) or in parallel.

Specifying tripsFor the defined lines, trips are entered;the time range, headway and trip type(with/without a payload) are determinedat the same time.

Entering depotsDepot parameters such as vehicle cap-acity and minimum dwell time can be entered.

Entering vehicle dataWhen the vehicles are specified, traintype, train number, minimum number ofvehicles and relevant information for thedepot can be selected.

Timetable exportEvery timetable can be converted into various exporting formats. This allows acontinuous workflow from planning tocontrol of operations.

Timetable importExternal timetables are automatically converted into internal vehicle schedules.

Global optimizationPowerful functions allow the minimisa-tion of energy consumption and passen-ger transfer times in complex railway networks simultaneously. Operationalfeatures such as cost-effective running,runtime reserves and departure timescan be flexibly adapted.



Falko GeoEfficient planning of new lines

For the planning of new lines, it is useful to be able to simulate various variants

in order to select the optimal solution. For this purpose, Falko offers the additional

module Falko Geo.

Possible applicationsFalko Geo is a program for editing tracktopologies for railway systems.

The track layouts are represented by means of a graph model consisting of nodes and edges. Falko Geo can be usedto create the configuration data requiredfor the Falko timetable design and valida-tion system within a short period of time.

For configuration of the desired sig-naling and safety system, you can finallyedit insulated block joints, loop margins,signals, routes, overlaps, speed profilesand gradient profiles by means of user-friendly entries. Using a series of graphi-cal analysis functions, such as speed andgradient profiles or properties of paths(lengths, runtimes), for example, theconfiguration can be finally checked.

Falko Geo is an editor for creating tracklayout design variants. It can be used tocreate and configure ...> routes> stations> changes in gradients> crossings> overpasses> entire signaling and safety systems

Not only trackside elements can be easilyentered in Falko Geo; overlaps and routescan also be automatically generated orindividually created or deleted. Using thezoom function, complex track layoutsspanning distances of many kilometrescan be viewed down to the very last de-tail.

An undo/redo function makes the plan-ning of projects easier.

Falko Geo allows all topology objects tobe easily entered with the project editorand also features an interface for im-porting speed and gradient profiles froma file. This means that a track topologycan be configured and modified even faster. Of course, all topology componentscan be freely opened and closed on a visual basis to enable the graphical representation to be adjusted dependingon the application involved.



Falko Timetable-ValidationEfficient operational planning

As in real lifeAnimated timetablesThe train runs in a timetable can be animated using a dynamic simulation.During the animation, the moving trainsare shown in the track layout display. The trains can be simulated with theirtrue length. The following states are additionally indicated:> Current signal colors> States of track vacancy detection

elements (clear/occupied)> Route states (set/not set)> Overlap states (set/clear)> Flank protection zones

(active/inactive)

Detailed testingPrecise timetable validationThe simulation of various signaling andsafety systems (e.g. electronic interlok-kings, continuous automatic train con-trol, automatic train control systems orthe European Train Control System), control systems and other factors, suchas passenger flows and energy consump-tion, enables operational sequences tobe realistically simulated.

The operational feasibility of a timetablecan thus be validated in detail. The possi-bility of activating different types of faultconditions enables the timetable’s sus-ceptibility to faults to be tested and mini-mized:> Speed restriction sections> Point and signal faults> Vehicle and door faults> Delayed entry movements
