Read l>eforo the Pennsylvania Street Railway Association, Oct. 11-12, 1899, byFrank SiUinian, Jr., tieneral Manager Scrauton Railway Co. In the design of a construction of track that has been used on thelines of thq Scranton Railway Co. to a considerable extent during1899, the two main points sought, were a rigid joint without theuse of an unduly heavy rail between the joints, and the employmentonly of such materials as are practically imperishable. The rail used was a 5-in. T section having a base of a width equalto the height of the rail, and weighing 57 lb. per yd., with a web3^ in. thick, and having parallel sides. The joint consists of theordinary six bolt joint that has been heretofore furnished with suchrails, except that it has been rolled to a little heavier weight. En-tirely in addition to this joint is what we claim to be a novel fea-.

Four of these rivets are of copper, and constitutebonds of the joint. As long as the rivets hold tight, this makes arail that is 10 in. in depth at the joints, securing a girder as deep asthe heaviest sections of rail that are rolled. Between the joints it is,of course, not necessary that the rails should be as heavy, and thegreat waste in the ordinary g-in. or lo-in. rail track construction isowing to the fact that there is so much of this great weight of railused in between the joints, in order that the joints themselves maybe of the necessary stiflfness and rigidity. Through the middle ofeach joint is a tie-rod, and every 10 ft. of track contains a tie feet apart and intermediately between the tie rod
