The airis conducted through the center pins,which are hollow, into the truck tran-soms, and thence to the motors. The en-gineers compartment at either end of thecab contains the operators seat, controll-er, air brake valves, bell and whistle ropes,ammeter, air gauges, sanders and othercontrol apparatus within immediate reachof the engineer. Report on Electrification by the SwissElectrification Commission The Swiss Electrification Commissionrecently made its report to the SwissGovernment, which is of great interestto our railroad systems, for it relates tothe possible electrification of nearly 2,000miles of track. This report has consid-ered the system best adapted for railroadservice and has come out strongly forthe single-phase system. 1 he various systems were considered,namely, the high voltage direct current,the three
