f the main switch, abovedescribed, while from a similar plate, fixed some short distancepast the points on the branch line, another wire is brought to points, he can, upon discovering his mistake, immediately puthis car-point switch to the off position, reverse the motor con-troller, and back out; then the conductor can release, by thekey referred to, the main switch in the street box, which will,of course, release the points. VERTICAL MOTOR-GENERATOR SETS A short time ago the Lend-Gastein (Austria) branch of theNeuhausen Aluminum Industrie Gesellschaft was equippedcompletely with electrical apparatus furnished by the OerlikonCompany, of Oerlikon, near Zurich, Switzerland. The mostinteresting feature of this installation is the use of verticalmotor-generator sets, of which there are six in all. This typewas chosen owing to the satisfactory service given by thevertical generators used in connection with the turbines in thisplant. It was found that the vertical arrangement permitted the

If the motorman desires to pass the junction without leavingthe main line, he simply keeps his car switch on the off posi-tion, and the points above and below remain unaffected. Shouldhe wish to turn into a branch line he must, on approaching thefirst contact stud, turn his switch to the on position. Currentthen flows from the line down the trolley, through the motor-mans switch, safety fuse, permanent resistance to the slipper,through the iron contact-plate to the closing solenoid of themain switch, thus closing this switch, and the large magnetbecoming energized pulls over the track and overhead switches. The car having passed the switches comes to the second con-tact-plate placed on the branch track. As the motormansswitch is still closed, a similar current flows through this plateto the
