The present invention discloses a seal and connection device between train compartments comprised of a Pi shaped rubber groove having two groove walls and a groove bottom. A width between the two groove walls is substantially equal to that of a slit between two neighboring compartments. The two groove walls can be fixed to ends of the two neighboring compartments respectively and the groove bottom are extended toward two ends thereof to form groove brims so that the groove brims can abut against end side walls of the compartments tightly. A slit between the compartments at the inner side of the train during swerving is narrowed a and a slit between the groove wall and the arc-shaped corners of the compartment is decreased, and the groove brims shift position with respect to the end side walls of the compartment inwardly; and a slit between the compartments at the outer side of the train during swerving is enlarged and a slit between the groove wall and the arc-shaped corners of the compartment is increased, and the groove brims shift position with respect to the end side walls of the compartment outwardly. With the above construction, a smooth hermetic connection between the compartments is achieved.
