Path Segments

Each train can retain its train number, category or rolling stock characteristics throughout the entire route. If one of these characteristics is to be varied for one or more sections of the train path, path segments can be used.

Path segments are used in the train editor to define a change in the train number, train category, rolling stock, or other characteristics of the trainset such as speed, weight or length.

Path segments are shown at the bottom of the train editor. They can be edited by first selecting the section, clicking on the arrival station and select one of the options, then editing the relevant characteristics in the table. To remove a path segment select the path segment and click Remove. The path segment will automatically be updated and the deleted segment incorporated in the segment above. If the first segment gets deleted, it will be incorporated in the segment below. It is not possible to have zero path segments.

The following symbols are used in the path segments:

• "-" -> reset, in other words not applicable, no information
• "|" -> keep, takes the same value as the previous path segment
• "*" -> Inhert from group, takes the same value as the relevant path segment in the train group, only relevant for trains part of a train group
• "(...)" -> override, the applied value is different than the one forseen by the train group, only relevant for trains part of a train group

The information organised in the path segment can be classified in two groups: Train information and Trainset information The Train information includes:

• Train number
• Train category
• Planned speed [km/h]
• Maximum speed in the timetable [km/h]

The Trainset information includes:

• Trainset
• Speed type
• Maximum speed of the trainset [km/h]
• Trailer length [m], excluding the length of engines
• Total length [m], including the length of engines
• Trailer weight [t], excluding the weight of engines
• Total weight [t], including the weight of engines
• Net weight percentage [%], as percentage of the net train weight, i.e. payload

The Train and Trainset information will be included in the running time calculation. Planned speed or maximum speed in the timetable can be used to force a required running time in certain sections within the automated calculation of the RTC. For now, trainset variations are only possible at OCPs where the train stops. Please check the paragraph below on not allowed combinations of trainset informations. If invalid values are inserted, the RTC will give an error message.

Simple best practice for Trainset information in the path segments: A freight train runs with single locomotive for the first part of its journey and gets a second locomotive for the last mountain climb. The wagons are 700m long and have 1200t of weight.

Invalid values for the trainset information

The trainset information interacts with and overwrites data which is normally defined in trenissimo. To understand if modifications to trainset informations are allowed, it is crucial to know how the trainset is structured in trenissimo. An in-depth guide to trainset configurations is available here (also note the subpages): https://trenolab.atlassian.net/wiki/spaces/TRENISSIMO/pages/1049060/Rolling+Stock+in+TRENO+and+trenissimo

An overview of allowed and not allowed trainset informations:

1. Trainset information overrides are not allowed for Trainsets consisting of Multiple Units.
2. Trailer length and total length cannot be lower than the values defined in trenissimo.
3. Either trailer length or total length can be defined, but not both. Similarily, either trailer weight or total weight can be defined, but not both.
4. If the Speed type is different in trenoLive and trenissimo, the value inserted in trenoLive will be used.
5. The Net weight percentage, expressed in numbers between 0 to 100%, refers to the net weight defined in trenissimo. If 10t net weight are defined and 50% net weight percentage are applied, trenissimo will calculate the RTC or simulation with 5t net weight. The net weight percentage is only available for trainsets consisting solely of Multiple Units or Engine + Wagons. It is not available for trainsets with Engine + Trailer. It is not possible to combine the net weight percentage value with total or trailer weight indications.
