This paper explores through-ticketing along the Northeast Corridor (NEC) of Amtrak to facilitate intercity rail services and intracity transit systems. The NEC, a vital transportation artery serving the densely populated region from Washington, DC to Boston, Massachusetts, presents a prime opportunity for enhancing passenger experience and increasing ridership through integrations of transportation modes. Through-ticketing, a worldwide transit strategy, allows passenger to purchase a single ticket throughout their entire journey, regardless of transfers between different modes of transportation. By implementing through-ticketing on the NEC, travelers would benefit from cheaper fare structures, reduced transfer times, and enhanced convenience. This paper examines the potential challenges and benefits of through-ticketing including coordination among multiple transit agencies, fare integration, and technological infrastructure. Overall, through-ticketing along the NEC holds promise for fostering a more seamless, efficient, and user-friendly transportation network, ultimately contributing to the region’s economic vitality, environmental sustainability, and social equity.
