SETTING POLES BY CONSTRUCTION TRAIN trolley wire is anchored by means of anchor ears and strainplates in two ways; on bracket construction, head guys arerun to the tops of the poles adjacent to the anchor strainplate and the anchor pole is held in alignment by means ofa brace pole. On the span construction the strain plates are guyed to the two adjacent poles on each side of theanchor span. The work of stringing and building the trolley wire inplace and obtaining its proper alignment was very greatlyexpedited by means of two kinds of tower the portions of the tracks with the least traffic, twobox cars were fitted up with collapsible platforms. Theseweredrawn by a locomotive and by having two flat carsplaced between them they were spaced so that two polescould be worked upon at a time. On the portions of theroads where the traffic was heaviest a light skeleton towerwith a collapsable top was mounted on four wheels. Thiswas of such weight that four men could lift it clea
