The invention discloses a sand spraying apparatus of a rail transit vehicle. The sand spraying apparatus comprises a sandbox and a sand sprayer, and also comprises an installation support, the end portion of the installation support is fixedly arranged on the inner wall of a vehicle body side beam, one end of the surface of the sandbox is detachably connected to the bottom of the installation support, and the other end is detachably connected to a vehicle body underframe; and the sand sprayer is connected with the outlet of the sandbox, the sidewall of the sand sprayer is connected with a pressure air tube for blowing sands in the sand sprayer down to a rail surface, and the pressure air tube is provided with a throttle valve for adjusting the air blowing amount. The installation position of the sandbox is shifted to a large space of the bottom of a vehicle through the transition of the installation support, so stable and ingenious installation is realized; and the sand spraying amount is adjusted through the throttle valve, so the adhesion coefficient between wheel tracks is increased, the idle running and sliding phenomena are reduced, the emergency brake distance is shortened, and effective transmission of an electric signal between the wheel tracks is protected. The invention also discloses a rail transit vehicle containing the sand spraying apparatus. The rail transit vehicle has the above described advantages.
