摘要： PROBLEM TO BE SOLVED: To provide a washing device, a washing method and washing particles for railroad vehicles having little influence on environment, and removing dirt attached to recessed parts of irregular faces at low cost. SOLUTION: When water F is sprayed from a nozzle 7d of a spray device 7, washing particles C in the spray water F impinge on the uneven face 3a of an outer plate 3 of the vehicle 2. The washing particles C can intrude into the recessed parts of the uneven face 3a, and easily intrude into the recessed parts of the uneven face 3a even if a spray pressure of the water F is low, and impinge on the surface of the recessed parts, as the water F can impinge on the surfaces of the recessed parts. Dirt D like iron oxide attached to the recessed parts of the uneven face 3a is removed from the recessed parts by the action of a physical force like shearing force applied to the dirt D, caused by impingement of the washing particles C on the dirt D. This washing results to dispense with high pressure spraying of the washing particles C onto the outer plate 3, to prevent intrusion of water into the vehicles or equipment through gaps of the vehicle 2.

摘要： PROBLEM TO BE SOLVED: To prevent generated heat from being accumulated in an elastic material, by arranging a heat radiating material by an elastic body therein, and bringing an end part of the radiating elastic material into contact with a wheel plate and a tire. SOLUTION: A hole 6 is provided to be inserted in an elastic material 5 with a desired space radially in a direction of an axle 1. A radiating material is only required to be an elastic body having good heat conductivity. A contact area in the periphery of the radiating material is preferably as wide as possible in an internal peripheral surface of the hole 6, and shape of a section is preferably an ellipse or rectangle. The radiating material thus formed is mounted in such a state of fitting to the internal peripheral surface of the hole 6, and a contact part is formed to make one end of the radiating material about on a wheel plate 2 and the other end about on a tire 3, respectively. In this constitution thus formed, friction heat generated when a brake is applied and heat generated when a vehicle overload repeatedly acts during running are transmitted to the wheel plate 2 and the tire 3 abutting in the contact part through the radiating material, thereby the heat can be prevented from being accumulated in the elastic material 5.

摘要： PURPOSE:To prevent easily crushed-stone of track bed on a track from scattering by laying and fixedly bonding a net unwound from a traveling truck traveling along a track rail and having reactive resin attached thereto to the crushed- stone of the bed laid on both sides of the track rail. CONSTITUTION:A traveling truck 3 is shifted to an execution place of crushed- stone of track bed. After nets 4 unwound respectively from rolls 6, 6, 6 pass through reactive resin W received in a resin tank 5 through guide rollers 7a, 7c, the nets 4 are guided out onto the crushed-stone of track bed 2 through the guide roller 7b. Next, while the traveling truck 3 is shifted along a track rail 1, the nets 4 having reactive resin W attached thereto are sequentially unwound and continuously laid on the crushed-stone of track bed 2. The nets 4 are heated by a heating means to harden the reactive resin W. thus, while the crushed-stone of track bed 2 is covered with the nets 4, the nets 4 are fixedly bonded to the crushed stone of track bed 2 so that the crushed-stone of track bed 2 is not scattered by the wind pressure or the like of a train traveling on the rail 1 with high speed.
