  Passenger trains represent a challenging environment in emergencies, with
specific evacuation conditions resulting from the typical layout and interior
design inherent to public transportation vehicles. This paper describes a
dataset obtained in a full-scale controlled experiment emulating the emergency
evacuation of a double-deck electric unit railcar carried out in Prague in
2018. 15 evacuation trials involving 91 participants were conducted under
various evacuation scenarios considering different compositions of passenger
crowd, exit widths, and exit types (e.g. egress to a high platform, to an open
rail line using stairs, and a 750 mm jump without any supporting equipment).
The study's main goals were to collect experimental data on the movement
conditions in the railcar and to study the impact of various boundary
conditions on evacuation process and total evacuation time. Movement
characteristics (exit flows, speeds) and human behaviour (pre-movement
activities, exiting behaviours) were also analysed.
  The data obtained was used to validate and adjust a Pathfinder model to
capture important aspects of evacuation from the railcar. Furthermore, a series
of simulations using this model was performed to provide sensitivity analysis
of the influence of crowd composition, exit width, and exit type on total
evacuation time. As a key finding, we can conclude that for the case of a
standard exit path (platform or stairs) the width of the main exit had the
greatest impact on total evacuation time, however, crowd composition played the
prevailing role in evacuation scenarios involving a jump.
