CHRONOLOGY  OF  MODERN  ELECTRIC  TRAIN  OPERATĨON.
 

           Elevated Railroad motors with either hand

           or scmi-automatic control,  and proposed

           to supply four or five months later, when

           developed, a  full  multiple unit control.

 April 20. 1898.—Spraguc bcgan opcrations 011 South

           Si<le road with  multiple unit system.

 Junc 18, 1898.—Spraguc  bcgan  operation  011 the

           Bririge enri of the Brooklyn "L" road.

 July 12. 1898.—Waterioo ít  City, Lontlon.  Straight

           rim  one  and onc-half  milcs, no mid-sta-

           tion.  Operatcs light  four-car train units,

           the two  end  ones being motor  cars with

           two  motors,  aiĸl  thc  mtcrmecĩiatcs bcing

           dcad cars.

 July 27, 1898.—Multiple unit systcm in ftill  operation

           011 South Side roatl. anri stcam abandoned.

                Equipmcnt on South Sitle road atter-

           wards Íncreascd to 180 cars. 150 of which

           arc fully  equipped, antl  ihirty. íor emerg-

           cncy scrviee,  partially equipped.

November  1,  1898.—Westinghouse  Company began
 

          to  put twenty  ears 011 thc Kings Coun-

          ty Elevated Railroad,  eacli equippcri with

          two sets  of two motors  with controlk-rs

          actuateri by air pisĩous ancl controllcd by a

          secondary eloctric circuit.  Four only out

          of the twenty cars are iu use at present and

          Eor locomotivc purposes.

i8t>8.—General Electric Company proposed six car

          trains antĩ rioublo locomotive cars for the

          Manhattan Elevated, and three car  irains

          witli a single locomottve car for thc Boston

          Elevated.

               And  finally the engineers of the Gen-

          eral Eloctríc and  Westinghouse companies

          arc  credited with the Íntention to operatc

          experimental muldple unit trains.

               Of cotirsc. there are a number of other

          proposals whĩch  havc been made both for

          multiple  unit and other systems, and for

          various roatls. of  which, however, mcntion

          is  untiocessary  for tlic present.
