It is supported on a cast steel underframeand is used with a Pacific type locomotive in passenger serv-ice. The photograph shows the appearance of the completedtank, the absence of rivet heads being particularly noticeable.

Text Appearing After Image: Fig. 2—All Seams in This Tender Were Joined by Electric Welding angles is shown by Fig. 1. This is a satisfactory methodas the welding can be done readily at reasonable cost andthe strength of the joint is in excess of that usually obtainedby the riveted type of construction. The side plates arebutt-welded and the tank braces and splash plates are after-wards securely welded to the side sheets. The whole con-struction results in a water-tight tank of good appearanceand great strength. In assembling the various parts of the tank, approxi- The welded method of construction eliminates the neces-sity of punching rivet holes in sheets, tees and angles andthere appears to be less likelihood of leaks developing inservice. It is expected, therefore, that the cost of maintenancewill be reduced.
