The California High Speed Rail Authority approved funding for Caltrain electrification and new grade separations on Tuesday morning. This is CHSRA’s contribution to a $2 billion plan that will improve the Caltrain passenger rail corridor, allowing for a mix of local, express and high speed trains along the tracks. Constructing a system where high-performance trains use both high-speed and conventional tracks is referred to as the blended service model or the network approach and it has been implemented successfully in countries around the world.
When designing a rail corridor using the network approach, it is critical to implement an efficient track layout. The track layout with high-speed trains on the outside and conventional in the middle provides an important benefit. This configuration allows for the most operational flexibility when dealing with service disruptions on any of the four tracks (as shown in the image above).
This track layout would also include a central island platform instead of platforms on each side of the tracks. Having a single platform makes finding your place to board simpler and also means you will not have to switch platforms when transferring between local and high-speed trains. One shared platform is typically twice the size of a standard platform and it also makes it easier and cheaper to provide all the platform amenities, such as ticket vending machines, benches, shelters, etc.
Some commuter rail lines were constructed with island platforms and additional exterior ROW, with the purpose of leaving room for future express or high-speed trains. The commuter rail corridor for the Metra Electric in Chicago was designed in this fashion. CrossRail Chicago
proposes taking advantage of the existing track layout and ROW to build additional tracks that could add capacity to the line. This additional capacity would allow for more frequent local service, express trains and provide a gateway for high-speed trains to enter Chicago’s Union
