The best of the trucks in usehave been retained, however, and are being strengthened in allof the weaker points, so as to withstand the shocks of startingthe motors, etc. Many of the odd trucks that came into useupon the system have been discarded, and replaced by newand stronger ones.

The accompanying drawing is typical of this truck recon-struction work, this one illustrating the changes that were madeupon a type of truck built by J. G. Brill & Company, which wasplaced in service upon the road in 1901. These trucks were de-signed for a much lighter service and slower speed than is nowin force, as at that time the traffic handled upon the elevated brackets are shown in heavy lines to indicate the constructionand relative locations. The channels are now bolted to massivelugs, which extend 12 ins. out from the bra
