Train control circuit and train

The invention discloses a train control circuit and a train, and relates to the field of train control, two switches and a third switch are arranged in each cab of the train, the first switch and the second switch are connected in parallel, the second switch and the third switch are connected in series, and the control circuit is arranged between a power supply and controlled equipment; the first switch is switched on when the driver's cab is activated, the second switch is switched off when any driver's cab is activated, and the third switch is switched on when the pantograph corresponding to the driver's cab rises and the high-voltage circuit breaker in the driver's cab is switched on. When the driver's cab is switched, the current direction for supplying power to the controlled equipment is changed from the first switch direction of the old activated driver's cab to the direction of the second switch and the third switch of the newly activated driver's cab and finally to the first switch direction of the n
