. Perno ferroviario elettrico. Vecchio filo tagliato, la bobina nel suo holderis attaccato alla parte posteriore del carro torre, ed è towedback al deposito. Naturalmente, quando il servizio lo consente, il trolley-wirestinging è fatto con una cabina a torre, che porta su di essa un filo metallico in modo che il conduttore possa essere estirpato in entrambe le direzioni. L'utilizzo del dispositivo descritto riduce la manodopera richiesta nelle bobine di carico e scarico, evita la necessità di prevedere un ulteriore paio di cavalli ed un conducente in caso di sostituzione del filo, sa

. Electric railway journal . old wire cut down, the reel in its holderis attached to the rear of the tower wagon, and is towedback to the storeyard. Of course, where the service permits, the trolley-wirestringing is done with a tower car, which carries a reelof wire on it so mounted that the conductor can bestrung out in either direction. The use of the device described reduces the labor re-quired in loading and unloading reels, obviates thereserving of valuable storage room for the extra wagon, saves the necessity of providing for an extra pair ofhorses and a driver in case of wire renewal, saves theannual interest on the investment and the maintenanceexpense of the above, saves the cost for the day oftheir use either hauling the reel to or from the work orstanding idly by waiting for the linemen to completethe work in hand before proceeding to another job, andshortens the actual time required for a given piece ofwork as compared with the old two-wagon method. All these items are felt to be worth considering in-.

If larger than No. 00 trolley wire is to be strung, orif extra long lengths can be put up producing a strainwhich might exceed the safe pull on the upper frameof the wagon, the reel holder can be trailed behindanother vehicle preceding the tower wagon and all thebenefits of the old two-wagon method of stringing besecured. This leading vehicle need be borrowed fromsome other job for but an hour or so, the emptied reeland holder being then left at the roadside to be towedback to the storeyard by the tower wagon at the end ofthe day. This, however, has never been done here. InSan Francisco, with the many ra
