abstract = {In the context of transport and energy transformation, the
aim is to increase rail transport, as it is significantly
more energy-efficient than road and air transport. The
prerequisite for increasing transport volumes in both rail
freight and rail passenger transport is the identification
and elimination of critical areas in order to ensure
sufficient performance and operational quality. To determine
the infrastructure’s performance and thus to identify
capacity bottlenecks, common methods can be applied. There
are recognised benchmarks to evaluate the determined
parameters. However, there is no generally accepted
definition of quality in railway operations. Such a
definition is necessary in order to identify and resolve
critical areas and thus improve the quality and
competitiveness of the rail network. Therefore, in this
paper a definition of quality and, based on it, a method for
the assessment of railway operation’s quality are
developed. Quality is defined in accordance with the
generally valid European standard on quality management
systems by the needs of stakeholders that are relevant for
railway operation. Based on these needs, the parameters
transport time quotient (timetable), occupancy time rate,
severity of delay, connection rate and train cancellation
rate can be derived. While most of the needs can be
represented by already existing parameters, the severity of
delay is defined as a new parameter for the evaluation of
delays and changes in delays. The definition of quality
levels for the selected parameters and the development of a
procedure for the combined evaluation of the parameters as a
set allow the identification of quality-critical areas in
railway networks. The knowledge of these areas is necessary
to implement targeted operational and infrastructural
measures for quality improvement. The developed procedure is
applied and validated on an example network. It demonstrates
how critical areas can be identified and resolved through
selected measures.},
