3. In a ear-heating apparatus having a main supply or train pipe beneath the car and a heating system within the ear, having portions thereof outside the car adjacent to the train-pipe, of spurs on said train-pipe in elose proximity to suoli exposed portions, and of a covering1 common to both of such pipes, substantially as described.

et. The combination of the circulating tem, a portion of which is exposed with the main steam-pipe and a portion of which is in proximity to the exposed portion ot' the eir- @plating` system to impart heat to the same, substantially as described.
