NAME

Travel::Status::DE::DBWagenreihung - Interface to Deutsche Bahn Wagon Order API.

SYNOPSIS

use Travel::Status::DE::DBWagenreihung;

my $wr = Travel::Status::DE::DBWagenreihung->new(
    departure => 'DateTime or YYYYMMDDhhmm',
    train_number => 1234,
);

for my $wagon ( $wr->wagons ) {
    printf("Wagen %s: Abschnitt %s\n", $wagon->number // '?', $wagon->section);
}

VERSION

version 0.11

This is beta software. The API may change without notice.

DESCRIPTION

Travel:Status:DE::DBWagenreihung is an unofficial interface to the Deutsche Bahn Wagon Order API at https://www.apps-bahn.de/wr/wagenreihung/1.0. It returns station-specific wagon orders for long-distance trains operated by Deutsche Bahn. Data includes wagon positions on the platform, the ICE series, wagon-specific attributes such as first/second class or family coaches, and the internal type and number of each wagon.

Positions on the platform are given both in meters and per cent (relative to platform length).

At the time of this writing, only ICE trains are officially supported by the backend, and even then glitches may occur. IC/EC trains are not officially supported; reported wagon orders may be correct, may lack unscheduled changes, or may be completely bogus.

METHODS

my $wr = Travel::Status::DE::DBWagenreihung->new(%opts)

Requests wagon order for a specific train at a specific scheduled departure time and date, which implicitly encodes the requested station. Use Travel::Status::DE::IRIS or similar to map station name and train number to scheduled departure.

Arguments:

departure => datetime-obj | YYYYMMDDhhmm

Scheduled departure at the station of interested. Must be either a DateTime object or a string in YYYYMMDDhhmm format. Mandatory.

train_number => number

Train number. Do not include the train type: Use "8" for "EC 8" or "100" for "ICE 100".

$wr->destinations

Returns a list describing all final destinations of this train. In most cases, it contains one element, however, for trains consisting of multiple wings, it contains one element for each wing.

Each destination is a hash ref containing the destination name and the corresponding platform sections (at the moment, this is a list of section identifiers).

This function is subject to change.

$wr->direction

Gives the train's direction of travel. Returns 0 if the train will depart towards position 0 and 100 if the train will depart towards the other platform end (mnemonic: towards the 100% position).

$wr->errstr

In case of a fatal HTTP or backend error, returns a string describing it. Returns undef otherwise.

$wr->origins

Returns a list of stations this train originates from. In most cases, this is just one element; however, for trains consisting of multiple wings, it gives the origin of each wing unless they are identical.

Each origin is a station name.

This function is subject to change.

$wr->platform

Returns the platform name.

$wr->sections

Describes the sections of the platform this train will depart from. Returns a list of Travel::Status::DE::DBWagenreihung::Section objects.

$wr->station_ds100

Returns the DS100 identifier of the requested station.

$wr->station_name

Returns the name of the requested station.

$wr->station_uic

Returns the international id (UIC ID / IBNR) of the requested station.

$wr->train_descriptions

Returns a list of hashes describing the rolling stock used for this train based on model and locomotive (if present). Each hash contains the keys text (textual representation, see $wr->train_desc) and sections (arrayref of corresponding sections).

$wr->wagongroup_description

Returns two strings describing the rolling stock used for this train based on model and locomotive (if present). The first one tries to be conscise (e.g. "ICE 4"). The second is more detailed, e.g. "ICE 4 Hochgeschwindigkeitszug", "IC 2 Twindexx mit elektrischer Lokomotive", or "Diesel-Triebzug".

$wr->wagongroup_model

Returns a string describing the rolling stock used for this train, e.g. "ICE 4" or "IC2 KISS".

$wr->train_numbers

Returns the list of train numbers for this departure. In most cases, this is just one element. For trains consisting of multiple wings (which typically have different numbers), it contains one element for each wing.

$wr->train_type

Returns a string describing the train type, e.g. "ICE" or "IC".

$wr->wagongroup_subtype

Returns a string describing the rolling stock model used for this train, e.g. "412" (model 412 aka ICE 4) or "411.S2" (model 411 aka ICE T, series 2).

$wr->wagons

Describes the individual wagons the train consists of. Returns a list of Travel::Status::DE::DBWagenreihung::Wagon objects.
