project, which buried 5.5 route-miles between North Bergen, N.J. and Hunterspoint, Queens by 1908, Taipei Main Station catalyzed urban redevelopment. Development was extensive but not without cultural costs. Modern office towers and underground malls replaced Japanese-era wooden shanties and wholesale outlets, but historic temples were preserved. Later phases completed the four track mainline tunnels, relocated yards to permit transit-oriented development (TOD), and provided a corridor for a much-needed crosstown expressway (Civic Boulevard). By 2008, US$5.8 billion were invested: Banqiao-Xike (16.0 miles) was tunneled, including all trackage within Taipei City, and Xike-Wudu (3.1 miles) was elevated under the TRA elevatization program. Nankang's Software Park, Exhibition Centre, and Xike's Science Park were developed around this time. Run-through services Taipei is Taiwan's capital and ultimate destination for TRA's mainlines. Explosive growth since 1980 made Taipei a 10-million population metropolis sprawled over four counties. To accommodate suburban commuters, and to serve passengers traveling to/from suburban business districts, Taipei was envisioned as a through station, allowing West coast trains to operate to Taipei's eastern suburbs, and vice versa. Through-running reduces platform occupancy times, maximizes one-seat rides, and distributes passengers over multiple stations, reducing crowding. Trains can be moved through Taipei's terminal district in arrival sequence, providing some delay absorption capability. Only ~20% of passenger trips originated/terminated at Taipei Main Station. Trains are turned at outlying yards (where turnback tracks are expressly provided), minimizing conflicting movements. Observation at Banqiao revealed substantial transfer activity between TRA and metro. In the 1990s, east coast trains terminated at Banqiao; WCML trains terminated at Nankang/Keelung. All trains thus operate over the busy Banqiao-Nankang (Bannan) section, effectively providing urban transportation by utilizing surplus capacity on longer-distance through trains. Commuter trains made all suburban stops, while Amtrak-like expresses stopped only at major hubs. These days, most East Coast services terminate at Shulin Station, which is the location of a major TRA yard. West Coast services mainly terminate at Qidu Station, which is the location of another large rail yard. Railway facility relocation To support metropolitan growth, Banqiao yard moved west to Shulin, and Nankang yard east to Qidu during the mid-2000s, extending through operations to approximately 10 miles either side. Banqiao, Taipei, and Nankang became major interchanges. Like Boston's NorthPoint project planned for a Boston & Maine yard, the former Banqiao yard is now Banqiao station and a successful TOD site. Like the CREATE (Chicago Region Environmental and Transportation Efficiency) plan, through-running
