Thistrain-pipe drains from the center to each end of the car,and at the middle point is a cross, 638. Two train-pipe valves, one at each end of the car, con-trol the passage of steam through the pipe, both beingkept open, except the rear one of the rear car, which isclosed to prevent the escape of steam. A small groove inthe seat of the valve provides for the continual drainingof the condensation in the train-pipe and avoids train-pipe valves are controlled by extension han-dles, which may be readily reached from the steps of the ?7i /.
