A heating floor panel unit of a railcar includes: a heater-equipped floor panel; a first flange horizontally projecting from one end of the floor panel in a car longitudinal direction and fixed to a carbody by a fastening member; and a second flange horizontally projecting from the other end of the floor panel in the car longitudinal direction and fixed to the carbody by a fastening member. The first flange and the second flange are located at such a height that upper ends of the fastening members are located below an upper surface of the heater-equipped floor panel. The first flange, as viewed from above, is located in such a manner that a position of the first flange in a direction orthogonal to a direction in which the first flange projects does not overlap a position of the second flange in the orthogonal direction.

A vehicle air-conditioning apparatus includes: a hot water heater core provided in a hot water circuit in which cooling water circulates in a heat source to recover waste heat of the heat source, and configured to exchange heat between the cooling water heated by the waste heat of the heat source and air to heat the air, thereby heating an inside of a vehicle by using the heated air; a heat pump configured to exchange heat between a refrigerant discharged from a refrigerant compressor and air by using an indoor heat exchanger to heat the air, thereby heating the inside of the vehicle by using the heated air; an electric heater configured to heat air to heat the inside of the vehicle; and a controller configured to select at least one of the hot water heater core, the heat pump and the electric heater to perform a heating operation.

An embodiment of the present disclosure provides an interior decoration structure and a railway vehicle with the interior decoration structure. The interior decoration structure is located inside a vehicle body. The interior decoration structure includes: a plurality of interior decoration components, the plurality of interior decoration components being spliced inside the vehicle body in sequence, wherein at least one pair of two adjacent interior decoration components are connected by an inserted-connected structure. The interior decoration structure in the present disclosure solves the problem in the related art that interior decoration parts are prone to unstable connection due to a mounting mode of an interior decoration structure.

A cladding arrangement includes at least one first cladding part for a vehicle, in particular a rail vehicle, which is connectable via at least one connecting device to a running gear of the vehicle, a running gear component, a car body of the vehicle or a car body component, wherein at least one first heating device, which is directed into a hollow formed by at least the first cladding part, is connected to the at least first cladding part to provide advantageous structural conditions such that ice deposits on the vehicle may be effectively thawed.
