A gladhand assembly includes a gladhand that rotates about a first axis with respect to a sealed housing. The sealed housing includes a lever affixed to the first axis to rotate as the gladhand rotates. A stop within the sealed housing may be configured into an engaged position in which it engages with the lever to lock the gladhand into a fixed position in which the gladhand cannot be rotated about the first axis. In addition, the stop may be configured into a retracted position to permit the lever to rotate and allow the gladhand to be rotated into a deployed position.

A leak control device includes a reservoir fluidly coupled with a brake pipe of a vehicle brake system. The leak control device also includes a conduit fluidly coupled with the reservoir and having an orifice that directs fluid out of the reservoir at a leak rate. The leak control device includes a valve fluidly coupled with and disposed between the reservoir and the conduit. The valve may open and direct the fluid out of the reservoir and out of the vehicle brake system at the leak rate responsive to a pressure of the fluid in the brake pipe being no less than a pressure of the fluid in the reservoir.

A position of a center of gravity of a vehicle body is easily optimized. An ABS modulator is disposed in a vicinity of a pivot bracket, which is joined to a lower rear portion of a main frame, and to which a swing arm is swingably connected.

A combined dirt collector and cutout cock (CDC & COC) device for a rail car control to prevent unintentional re-pressurization of the control valve and rail car braking system. The device has an inlet configured for interconnection to an air supply, an outlet configured for interconnection to a control valve of a rail car, a valve moveable between a first position where an inlet is connected to an outlet and a second position where the inlet is isolated from the outlet, and a control valve vent positioned downstream of the valve and configured to open in response to the valve being moved into the second position. The valve may include a ball having a first passageway for selectively connecting and disconnecting the inlet from the outlet and a second passageway formed therethrough that is positioned to interconnect the outlet with the vent when the valve is in the second position.

A tube fitting includes: a zinc-based plated layer; and a resin coating layer that is positioned at an outermost surface at an outer side of the zinc-based plated layer and includes a polyethylene substance, a lubricant, and solid particles. When a fitting average plating thickness t relating to the thickness of the zinc-based plated layer is defined, 2.1<t<19.7 is true.

A retarding control assembly for a brake valve may include a bleed line configured for arrangement between a spring chamber of a brake command assembly and a tank line. The bleed line may include a check valve configured to allow fluid flow from the spring chamber to the tank and a check valve bypass configured to allow fluid flow from the tank line to the spring chamber passed the check valve and defining a restricted pathway.
