The piping extends to theother end of the car X and then turns and in a seriesof loops, each one being under a seat, returns to point a,thence it crosses to the other side. The hot water is thusconveyed from one end of the car to the other, backagain in a zig-zag circuit along the same side, thenceacross the car to the other side, and down the pipe p toX as before, back again as on the other side to the returnbend at Y, recrosses the car at b and thence re-enters theheater at the bottom of the coil at b.
