(Continued from February.) In connection with block signal systems for interurbanroads the track instrument recently put into use on theMetropolitan West Side Elevated Railroad of Chicago willbe of interest. Various complicated contrivances for mak-ing an electrical connection by the passage of the wheels ofa train have been proposed and put into use from time totime. This one, however, is the acme of simplicity. It isused on the Metropolitan for giving annunciator signals atthe stations telling of the approach of trains, but can alsobe used for block signal purposes. The accompanyingdrawing will make the plan plain. A piece of timber islaid just outside one rail, and on it is a strip of flat steel J4by 2 in. Under the timber is rubber to afford a METROPOLITAN TRACK CONTACT. The steel strip on top of the timber is a little above the levelof the rail. The annunciator wire is connected to the steelstrip and the passage of the car wheels connects it toground. The Hamilton & Dayton Fast Line between Hamiltonand Dayton, O., is operated by two companies; from Day-ton to Miamisburg, ii >i miles, by the Dayton TractionCompany and from Miamisburg to Hamilton, 27 miles, bythe Cincinnati & Miama Valley Traction Company. Thesetwo companies have the same president and the same gen-eral manager, and are soon to be consolidated. Throughthe courtesy of the general manager, W. G. Wagenhals, wehave received a description of the block signal systemwhich has been in use on the line for over a year. The turn-outs are located about two and one-half milesapart, and at each one is placed a signal box located on apole sufficiently near the track so that the motorman canthrow the switches without leaving the car, although
