Method for checking a braking system of a railway vehicle, wherein the railway vehicle comprises a plurality of brake reservoirs for controlling braking elements on the basis of an internal pressure in the brake reservoir, and wherein the internal pressure in the brake reservoirs is controlled by one or more central brake lines, the method comprising the following steps: a. connecting the one or more central brake lines to a fixed or mobile compressed air unit; b. applying a predetermined, pre-programmed pressure regime for checking from the fixed or mobile compressed air unit on the one or more central brake lines, whereby the regime follows a pre-programmed course; c. checking that the braking elements of the railway vehicle are engaged; d. controlling the central brake lines to obtain a pressure level at which the brake reservoirs disengage the braking elements; e. checking that the braking elements of the railway vehicle are disengaged; characterised in that a pressure-regulating system is provided between the one or more central brake lines and the fixed or mobile compressed air unit, wherein the pressure-regulating system is adapted for monitoring the pressure from the fixed or mobile compressed air unit in the central brake lines and for exercising the predetermined regime of pressure, and wherein the central brake lines are controlled via the pressure-regulating system for obtaining the pressure level at which the brake reservoirs disengage the braking elements, the pre-programmed course comprising at least the following phases: rapid pressure rise, rapid decrease of pressure, slow rise in pressure, slow pressure drop, and a constant phase of pressure; wherein the pre-programmed course of the pressure regime comprises the following substeps: i. a first substep in which the pressure is increased at a first speed, to a predetermined pressure level and/or during a predetermined time period; ii. a second substep in which the pressure is increased at a second speed, to a predetermined pressure level and/or during a predetermined time period, whereby the second speed is lower than the first speed; iii. a third substep in which the pressure is reduced at a third speed, to a predetermined pressure level and/or during a predetermined time period; iv. a fourth substep in which the pressure is reduced at a fourth speed, to a predetermined pressure level and/or during a predetermined time period, whereby the absolute value of the fourth speed is lower than the absolute value of the third speed; v. a fifth substep in which the connection between the one or more central brake lines and the fixed or mobile compressed air unit is closed during a predetermined time period; whereby checking that the braking elements of the railway vehicle are engaged is performed during a substep in which the pressure is reduced from a pressure level higher than the pressure level at which the braking elements disengage, to a pressure level lower than the pressure level at which the braking elements disengage, preferably during the substep in which the pressure is reduced at the speed with the highest absolute value. a. connecting the one or more central brake lines to a fixed or mobile compressed air unit; b. applying a predetermined, pre-programmed pressure regime for checking from the fixed or mobile compressed air unit on the one or more central brake lines, whereby the regime follows a pre-programmed course; c. checking that the braking elements of the railway vehicle are engaged; d. controlling the central brake lines to obtain a pressure level at which the brake reservoirs disengage the braking elements; e. checking that the braking elements of the railway vehicle are disengaged; i. a first substep in which the pressure is increased at a first speed, to a predetermined pressure level and/or during a predetermined time period; ii. a second substep in which the pressure is increased at a second speed, to a predetermined pressure level and/or during a predetermined time period, whereby the second speed is lower than the first speed; iii. a third substep in which the pressure is reduced at a third speed, to a predetermined pressure level and/or during a predetermined time period; iv. a fourth substep in which the pressure is reduced at a fourth speed, to a predetermined pressure level and/or during a predetermined time period, whereby the absolute value of the fourth speed is lower than the absolute value of the third speed; v. a fifth substep in which the connection between the one or more central brake lines and the fixed or mobile compressed air unit is closed during a predetermined time period;
