The present disclosure provides an auxiliary air cylinder inflation system and an air brake system for an express freight train, and relates to the field of air brake systems, aiming to improve the problem that the auxiliary air cylinder inflation is subject to the control air cylinder inflation. The auxiliary air cylinder inflation system comprises a control air cylinder inflation valve, a control air cylinder, an auxiliary air cylinder inflation valve, a first passage and a second passage; the control air cylinder inflation valve is provided with a train pipe air outlet, and the control air cylinder is provided with a first train pipe inflation port, and the auxiliary air cylinder inflation valve is provided with a second train pipe inflation port; and the first passage communicates with the train pipe air outlet and the first train pipe inflation port, and the second passage communicates with the train pipe air outlet and the second train pipe inflation port; and the first passage is connected in parallel with the second passage. The air brake system for an express freight train comprises an auxiliary air cylinder inflation system. The control air cylinder and the auxiliary air cylinder inflation valve can be simultaneously inflated through the first passage and the second passage, the auxiliary air cylinder inflation valve inflates the auxiliary air cylinder, and the auxiliary air cylinder inflation valve and the control air cylinder are separately and independently inflated, which is not restricted by the control air cylinder inflation.
