Any transit authority that finds itself in the position that PAT was in before design and construction of catenary systems must make a choice. The authority can put time, effort, and money into development of a standardized system that will precisely meet their criteria at the very outset of a project thus ensuring competitive prices, consistency in supply and installation, and future availability of material. Or, an authority can choose the cheapest initial course using available equipment and installation techniques that can easily lead to high material and construction costs. The latter can also lead to an overdependence on limited sources; and, should a sole source "dry up" unexpectedly, construction or maintenance, or both, will suffer. The Pittsburgh LRT system is a good argument for the first choice. A standardized catenary system was developed and was made to be easily manufactured and installed. Prices were competitive and equipment was quickly available from any number of sources. In addition, the authority had enough time in the planning stages to modify equipment to suit any requirements specific to the location, and there was sufficient time during the preparation of contract documents to become familiar with the detailed workings of the system. Planning and designing ahead in this manner have benefited the authority on all levels. (Author)
