The invention belongs to a rail train hydraulic braking system slow release device in the technical field of rail trains. The invention further relates to a control method of the rail train hydraulic braking system slow release device. The reversing valve module (A) comprises a shuttle valve (1), a first pressure switch (2) and a second pressure switch (3), the manual pump module (B) comprises a manual pump (4), an oil tank (5) and a pressure release valve (6), the shuttle valve (1) is communicated with the oil tank (5) through a first pipeline (7), the manual pump (4) is arranged on the first pipeline (7), the shuttle valve (1) is communicated with an auxiliary relieving unit (9) through a second pipeline (8), the shuttle valve (1) is communicated with a clamp (11) through a third pipeline (10), and the first pipeline (7) is communicated with the pressure release valve (6). The slow release device of the hydraulic braking system of the rail train is easy and convenient to operate, relieving and braking can be reliably completed, risks caused by misoperation and forgetting to restore gears are effectively prevented, and the false activation probability is reduced.
