STANDARD TRACK CONSTRUCTION To complete this article and possibly make clearer thepurposes of the different track machines described, sectionsof the companys standard track construction and pavedstreets are presented. The present standard rail section isthe Lorain No. 104-422, with 36-in., twelve-bolt bridge-trussangle plates. For the past two years the company has been usingtitanium steel rails and insists upon having all angle platesfor these rails rolled from titanium metal also. This prac-tice is followed because the company has found that theseplates stand up much better than when angle plates of softermetal are used. These softer plates would tend to crush. San Francisco Track—Side and End Views of Sand Elevator Equipment Built by the Company to Take Sand from Dunes in the Suburbs of San Francisco into a chute on the opposite side of the elevator. It thenpasses into the car to be loaded, which is on another trackparallel with the loading track. The force required tooperate this elevator is one operator and one laborer at theend of the elevator. The sand bank from which the company gets most of itssand is located in the suburbs of San Francisco on Twen- down or flatten out under the end of the receiving rail, andthis condition would be followed by cupped joints. As yetthe company has not experienced any corrugation on thetitanium rails, although corrugation is frequent on the or-dinary rails on account of the steep grades throughout thecity and the consequent necessity for the frequent use ofthe braking equipment. 468 ELECTRIC RAILWAY JOURNAL [Vol. XLI, No. ii.
