so that the desired service can be achieved. Amtrak has limited resources for capital investments outside the NEC, so the National Passenger Railway Agency must build up the funds. Typical sources are public transportation obligations, a large number of public and local assistance programs, and sometimes federal funds from the free trade agreement or the federal highway administration (for grade improvement). Significant funds have recently been released by PRIIA and ARRA through the FRA. In some cases, a state will link people and freight funding programs into a package of improvements. Note that the source of funding has no influence on whether the service is classified as a commuter or interurbai amtrak. The capital improvement agreement with freight railways will repeat the specialization of services, including the planned gradual development. Next, the Passenger Railways Agency and the railways will agree on the specific improvements needed to support a number of routes, travel times and OTPs. For phased development, the agreement defines each phase by the specialization of services and the corresponding improvements in infrastructure. It is essential to link specific improvement projects (1) to specific frequencies, travel times and punctuality metrics, duly supported by analysis results and accepted by the Amtrak freight train and the Passenger Railway Agency, and (2) with measures defined by the host railway in the event of non-compliance. Table 4-3 shows perfor-Mance service metrics that have proven effective in achieving good service quality.
In the absence of an applicable agreement, investments in infrastructure are seriously unlikely to bring the expected benefits. The National or Regional Passenger Railway Agency should complete with the Freight Railway a master contract on the basic link between improvement projects and passenger journeys, time and journey, as well as a “task-command” mechanism for the implementation of individual projects. The Passenger Railway Agency normally contracts with the freight railway to carry out the project. The railways will carry out the project with their own maintenance workers or with contractors at their discretion. As a general rule, freight railway employment contracts contain provisions relating to the use of contractors and the railways must comply with these agreements.
