An end carriage for a railway vehicle extends between a first free end and a second end intended to be connected to another carriage of the railway vehicle, the end carriage including a lower housing for a bogie made in proximity to the first end.

The end carriage further includes at least one conduit, opening on the one hand into the lower housing, and opening on the other hand into the first end of the end carriage, and means for circulating air in the conduit.

Overhead passenger comfort modules are provided with a module segment having a support frame member which includes a perimetrical trim frame member, and a ventilation system supported by the support frame member. The ventilation system includes a supply conduit adapted to being fluid-connected to a supply of ventilation air, and first and second branch conduits fluid-connected at one end to the supply conduit and terminating in elongate first and second ventilation openings at first and second edge regions of the support frame member. First and second concavely curved edge diffuser portions are provided which are adjacently positioned to and spaced from the first and second ventilation openings respectively. Ventilation air discharged from the first and second ventilation openings will therefore impinge on the concavely curved first and second edge diffuser portions so as create a diffused volume of air which envelops substantially a passenger seated therebelow and establish a personal ambient air zone for the passenger.

A rail vehicle has a return flow path structure formed by a lower tube portion, an upper tube portion, a seat, and an opening or a notch of a seat base. When air flows from the inside of a vehicle cabin to an exhaust port connected to an exhaust air flow path under a floor via the return flow path structure, a direction of a flow passing between an outer periphery of the lower tube portion and an inner periphery of the upper tube portion is opposite to a direction of a flow passing through an inner side of the lower tube portion.

A ventilation system for a passenger transit vehicle that comprises a passenger compartment. The ventilation system comprises a variable speed fan for providing outside air to the passenger compartment, wherein within a given ambient temperature range, the speed of the variable speed fan is controlled such that the air speed produced by the variable speed fan increases with increasing ambient temperature. The ventilation system further comprises a duct system fluidly connecting the variable speed fan to an air diffuser that directs the air from the variable speed fan towards the passengers within the passenger compartment. The cross sectional area of the duct system decreases along its length for providing substantially constant air pressure along its length. The ventilation system is able to provide outside air into the passenger compartment at an air flow speed of greater than 0.15 m/s.

A refrigerated transport container includes a refrigeration unit and an airflow guidance structure for distributing cooled air throughout the refrigerated transport container. The airflow guidance structure includes a front panel section that is affixed at a front end of an interior ceiling of the refrigerated transport container, and that receives cooled air from a fan outlet of the refrigeration unit. A series of additional panel sections are affixed along the interior ceiling of the refrigerated transport container from the front panel section to the back of the refrigerated transport container. The panel sections together form an air channel at the interior ceiling of the refrigerated transport container that conducts air from the front end to the back end, and allows for passage of cooled air from the air channel out to an interior of the refrigerated transport container.

Vent cover assemblies for a railway car are shown and disclosed. In one embodiment, the vent cover assembly includes a base housing having opposed first and second end portions. The second end portion includes opposed first and second walls and an opening therebetween. The first wall includes a first slot and the second wall includes a second slot. The vent cover assembly additionally includes a cover that spans the opening and includes opposed first and second tabs. The first tab is sized to be received in the first slot and the second tab is sized to be received in the second slot.
