A logic control system for magnetic track braking of a rail transit vehicle includes a magnetic track braking control circuit, a magnetic track braking power supply execution circuit, and a magnetic track braking status monitoring and feedback circuit. The magnetic track braking control circuit includes a pneumatic actuator relay, an electromagnet relay, a system protection relay, a power-on delay relay, a power-off delay relay, an automatic control branch circuit, and a manual control branch circuit. The pneumatic actuator relay is connected to the power-on delay relay, and the system protection relay is connected to the power-off delay relay. The automatic control branch circuit includes a first isolation magnetic track braking switch and an emergency braking relay contact. The manual control branch circuit includes a first circuit breaker, a cab signal option switch, a second isolation magnetic track braking switch and a manual touch button.
