Arrange all heavy pieces ofapparatus so that their centers ofgravity lie in the center of the car,or symmetrically placed to it, and asnear the earth as possible. (3) All apparatus mounted abovethe car floor should be as light as itsdesign will permit. (4) Make the overhead trolleycontact above the car, in preferenceto the side of the car. (5) Support the motors flexibly onthe axles of the trvicks. (6) Give the front end of the cara wedge shape. (7) Support the car body on thetruck frame at some distance fromthe center bolt, and allow it a flexi-bility in a line at right angles to thetrack, independent of the truck. (8) Make the total wheel liase ofthe truck of ample dimensions andnot less than 20 per cent of thelength of the car. (9) Build the road as straight aspossible, and where more than onetrack is used make them furtherapart than present practice wouldsuggest.
