With wheels mated according to their tape sizes, fin-ished bore smooth and true, the center line of the wheel co-incident with the center line of the axle upon which it ismounted, with truck square and brake rigging kept inproper adjustment, it is reasonable to expect a large mile-age and low expense in maintenance and repair. Since the Schoen Steel Wheel Company was purchasedby the Carnegie Steel Company, in July, 1908, it has beenthe constant endeavor to standardize so far as possible typesof wheels for street railway, interurban and elevated rail-road service. A number of standard street railway wheelshave been designed in accordance with the recommenda-tions of the American Street & Interuban Railway Associa-tion, with the essential purpose in view of decreasing thecost of manufacture and making these wheels economicalto use under all conditions of service. ELECTRIC SWITCHING DEVICE FOR STREET RAILWAYS. The C. W. Squires Manufacturing Company, Beverly,Mass., is placing on the market a new electric switching de-vice for street railways, which has been given a thoroughtrial on a number of roads in New England during thepast year, among them the Connecticut Company and theBoston & Northern Stret Railway. The mechanism hasbeen designed with the view of obtaining simplicity andpositive action. As will be seen from the accompanyingsectional drawing, the switch tongue is moved by a double-acting solenoid magnet which stands in a vertical position,thus doing away withfriction and wear onthe magnet tube. Theplunger of the solenoidis connected to one armof a pivoted bell the other arm ofthis crank is attacheda yoke and adjustingscrew connected to theswitch tongue. Theoperating magnet is suspended in a section of standarddrain tile below the bottom of the switch box. No sewerconnection is needed, as the solenoid will operate equallywell if covered with water. A
