Graphic Timetable

The Graphic timetable is the visual presentation of all trains on a specified corridor and a specified interval of time. To change these axis parameters use the search functions to the left. The graphic timetable shows additional train informations, too, such as margins, conflicts and line tracks. It helps the planner to understand the timetable situation and consequences of potential modifications to the service concept.

Moving around in the diagram

To move the diagram horizontally or vertically, drag and drop the mouse over the diagram. To zoom in press SHIFT and draw a rectangle on the area of interest. To zoom out again use the return function to the left of the search function. It is possible to return to one of the previous 5 visualisations by the adjacent history menu. It is also possible to return to a broader view by setting different search criteria.

Compare scenarios

The Compare function allows comparision of two timetable scenarios in the same project. Select the scenario to compare and a viable compare date. The date needs to be in the validity period of both scenarios. By adjusting the stroke lines style a visualisation of overlaping services is guaranteed. Train paths of the compared (external) scenario are always displayed as dashed lines.

Filter trains

Trains can be filtered using the options presented there. The filtering only deactivates the visualisation of trains not meeting the filter criteria. You can use collections for a userdefined visualisation. Activate the Filter by collection toggle to visualise User and Scenario collection settings. Be aware that certain Filter and Compare settings should not be activated together, because they might be conflicting and could render the visualisation incomprehensible.

Selected trains

Normally, the user can select one train in the diagram to highlight its path. If the multiple selection is activated, a number of trains can be selected by clicking on the path consecutively. Only trains visible in the diagram can be selected.

With the function Shift trains the trains will be moved by the inserted amount to the left (back in time) or to the right (forth in time). Be aware that trains can not start before 00:00:00, but they can start after 24:00:00. Shifting a train can or can not have an effect on the other courses of the train group. This depends whether the Edit train group toggle is active or not. If it is deactivated, only the individual, selected trains are moved. If trains are moved, already established connections can turn invalid.

With a double click on the train the train editor opens. With a single click on the dots of a selected train a reduced version of the train editor appears as a pop up to allow modifications to running or stop times. With a right click on a train the context menu opens presenting various editing options.

Drag and drop modifications

Trains can be modified by using the drag and drop function. The drag and drop only works when pressing Shift + Alt. There are three ways to modify the train:

1. Shift the train. This only modifies the Departure time art the first OCP and shifts the train by a defined amount.
2. Extend run time. This adds run time margin in a certain section between two OCP. Select the train and drag and drop the beads.
3. Extend stop time. This adds stop time margin at a certain OCP, with an Entry type other than PASS. Activate the Path entry types and the margins visualisation in the Settings and drag and drop the entry type rectangles.

You can set the drag editing precision threshold to either 1s, 30s, 60s or 300s. If the threshold is set to 60s, only multiples of 60s, i.e. 60s, 120s, 180s, etc. are added to the timetable. The drag editing threshold is defined in the Settings. Further it is necessary to specify which travel and stop margin are edited in the process. This is particularly relevant if multiple margins are present. We strongly advise only to select margins that are expressed in seconds.

Settings

Visualisation settings can be used to display additional information or change the layout of the timetable graph. The Blocking times and Show conflict options can only be used in combination with other functions. For the visualisation of blocking times the RTC is a requirement. For the visualisation of conflicts an executed check in the Conflict checker is necessary.

Blocking times

Blocking times visualise the planned occupation time of the train on microscopic infrastructure elements (train detection sections). The information is part of the RTC and the microscopic model in trenissimo. It is necessary to set the correct section deviders (insulated joints or axle counters), the correct route settings (overlaps, reserve time, release time) and the correct release logic (i.e. partial route releases) to obtain precise results. Additionally, the running time calculation itself has an impact on the blocking times as well.

Blocking times can be visualised in two ways:

1. As Calculated - Taking the pure result of the RTC and the abovementioned interlocking characteristics
2. As Planned - Adding the planned travel and stop margins into account, too.

Usually, the "Planned" visualisation is the advised setting, as it follows the line representing the train trajectory in the graphic timetable. If the "Calculated" visualisation is selected and the timetable has additional margins, the blocking times might not overlap with the planned trajectory of the train.

Conflicts

Conflicts are shown where they arise. They are colour coded, meaning:

• red: Clashes - two trains on the same infrastructure element
• blue: Run times - it is likely that the trains will either be much faster or much slower than the planned times
• orange: Trainset length too long for stations or platforms
• yellow: Timing problems - it is likely that the trains will hinder each other in operation
• grey: Missing information
• turquise: Unbalanced connection
• purple: Time not sufficient - either for stops or turnarounds

Further visualisation settings

1. Train colour, by

• Train colour or train group colour, these are defined in the train editor directly
• Category, the category colour is defined in the Scenario
• Operating Company (TOC), the TOC colour is defined in the Scenario
• Line track, the Line track colour is defined in the Line details editor in the Infrastructure model.

The colours present in the diagram are included in the Colours legend accessible in the right upper corner of the page.

2. Scheduled path details

• Train code, as label on the train path
• Train number, as label on the train path
• Margins, as colored shapes (triangles for travel margins, rectagles for stop margins). The colour for the margins is set in the Projects.
• OCP times, as full minutes, departures only, as label on the train path.
• Path entry types, as small squares indicating the path entry type other than PASS.
• Trainset description, as label on the train path

It is advised not to activate all details at once, as it will overload the diagram with information.

3. Capacity restrictions (TCR)

Visualises the TCR in time and space.

• Possession of line track, red
• Speed restriction, yellow
• Axle load restriction, purple
• Train length, orange It is possible to access detailed TCR information and the TCR editor with a double click on the TCR label.

4. Corridor axis

On the corridor axis (spatial coordinates) the OCP of the Corridor are visualised. It is possible to deactivate some OCP groups, when they are not relevant for the diagram. The OCP groups are further defined by font colour and style. Additionally, the distance can be shown, either in absolute km, relative km between OCP or both. The distance is taken from the macroscopic model and converted into km. Respectively, a conversion into miles is also possible via the user settings.

5. Grid on time axis

The grid ("time lines display format") are automatic or user defined gridlines on the time axis. The user-defined grid allows three different levels of gridlines, the interval is given in minutes.

Lastly, the background colour can be user-defined, too.
