Proposed changes
According to its long-range plan published in 2006, the WSDOT Rail Office plans eventual service of 13 daily round trips between Seattle and Portland and 4–6 round trips between Seattle and Bellingham, with four of those extending to Vancouver, British Columbia.[101] Amtrak Cascades travels along the entirety of the proposed Pacific Northwest High Speed Rail Corridor; the incremental improvements are designed to result in eventual higher-speed service. According to WSDOT, the "hundreds of curves" in the current route and "the cost of acquiring land and constructing a brand new route" make upgrades so cost-prohibitive that, at most, speeds of 110 mph (177 km/h) can be achieved.
The eventual high-speed rail service according to the long-range plan should result in the following travel times:
In order to increase train speeds and frequency to meet these goals, a number of incremental track improvement projects must be completed. Gates and signals must be improved, some grade crossings must be separated, track must be replaced or upgraded, and station capacities must be increased. The existing Columbia River Railroad Bridge between Vancouver, Washington and Portland would have to be modified, and an additional railroad bridge would have to be built next to the existing bridge.
Building upon previous studies, the long-range plan also proposed relocating the northern terminus from Vancouver's Pacific Central Station southeast to a "Greater Vancouver Terminal" near SkyTrain's existing Scott Road station in Surrey, British Columbia. In this scenario, northbound passengers would then ride the SkyTrain rapid transit system for about a half-hour to complete a trip to downtown Vancouver.[102][103] The plan cited several motivations for terminus relocation, including: congestion at and near the New Westminster Bridge, which is a single-track railway subject to very low train speed limits and numerous bridge openings for marine traffic; lower-than-desired speed limits due to poor geological soil conditions underneath the BNSF track between the bridge and Pacific Central Station; bottlenecks at Canadian National Railway's Second Narrows Rail Bridge and Thornton Tunnel that cause northbound freight trains headed to the North Shore of the Burrard Inlet to back up onto and obstruct the BNSF main line; and repeated opposition to passenger service expansion from Canadian National Railway.[104]
In order to extend the second daily Seattle to Bellingham round trip to Vancouver, BNSF was required to make track improvements in Canada, to which the government of British Columbia was asked to contribute financially. On March 1, 2007, an agreement between the province, Amtrak, and BNSF was reached, allowing a second daily train to and from Vancouver.[105] The project involved building an 11000 ft siding in Delta, British Columbia, at a cost of US$7 million; construction started in 2007 and has been completed.
In December 2008, WSDOT published a mid-range plan detailing projects needed to achieve the midpoint level of service proposed in the long-range plan.[106]
In 2009, Oregon applied for a $2.1 billion Federal grant to redevelop the unused Oregon Electric Railway tracks, parallel to the Cascades' route between Eugene and Portland.[107] But it did not receive the grant. Instead, analysis of alternative routes to enable more passenger trains and higher speeds proceeded. In 2015, the current route, with numerous upgrades, was chosen by the Project Team as the Recommended Preferred Alternative.[108] The Preferred Alternative, if built, would decrease the trip time by 15 minutes from 2 hours and 35 minutes to 2 hours and 20 minutes and increase the number of daily trains from 2 to 6 from Eugene to Portland.[109]
In 2013, travel times between Seattle and Portland remained the same as they had been in 1966, with the fastest trains making the journey in 3 hours 30 minutes.[110][111] WSDOT received more than $800 million in high-speed rail stimulus funds for projects discussed in the mid-range plan, since the corridor is one of the approved high-speed corridors eligible for money from ARRA.[112] The deadline for spending the stimulus funds is September 2017. The schedule was for the Leadership Council to vote on this in December 2015, then a Draft Tier 1 Environmental Impact Statement was to be released in 2016 and hearings held on it, for the Leadership Council to finalize the Recommended Selected Alternative in 2017, then publish the Final Tier 1 EIS and receive the Record of Decision in 2018.[113] Then if funds can be found, design and engineering must be done before any construction can begin.
In October 2023, WSDOT made public a summary of its preliminary service development plan, which offered five conceptual options for future rail service. Three of the options kept the top train speed at 79 mph, while the other two options increased the top speed to 90 mph. The most aggressive frequency option increased the number of round trips between Seattle and Portland to 16 and the number between Vancouver, British Columbia, and Seattle to 6. Four of the options included a rail/bus combination for some round trips between Vancouver and Seattle; the section between Seattle and Bellingham would be served by rail, while the section between Bellingham and Vancouver would be handled by bus.[114][115] The assumed maximum top speed was reduced from 110 mph in the 2006 long range plan to 90 mph in the 2024 preliminary service development plan based on BNSF restrictions.[116]
Various jurisdictions have made attempts to add a stop within the approximately 60 mi gap between Vancouver, British Columbia, and Bellingham. The intent was to better serve the growing population in the southern part of the Greater Vancouver region without requiring a backtrack to downtown Vancouver. Infill stations have been proposed on separate occasions at the international border towns of Blaine, Washington,[117] and White Rock, British Columbia,[118] which both had stops on Amtrak's predecessor Pacific International service.[119]
In 2024, a Canadian passenger rail advocacy group recommended that the Canadian government make 10 infrastructure improvements between White Rock and Vancouver at a total estimated cost of CA$127.6million. These improvements would increase operational performance and reliability, and the resulting reduction in travel time would permit Amtrak to add a Blaine stop.[120]
- Seattle to Portland – 3:30 (2006); 3:25 (after completion of Point Defiance Bypass); 2:30 (planned)
- Seattle to Vancouver, British Columbia – 3:55 (2006); 2:45 (planned)
- Vancouver, British Columbia, to Portland – 7:55 (2009); 5:25 (planned)
