Caltrain Modernisation Program delayed until 2024; costs rise by USD333 million, US [free access]

June 4, 2021

Caltrain has announced that the electrified service on Caltrain, a key component of the Caltrain Modernisation Program, has been delayed from 2022 to late 2024. The main reason for the delay is the disruptions to supply chains caused by the ongoing COVID-19 pandemic.


Additionally, the estimated cost of the project has increased by USD333 million, from USD1.98 billion to USD2.3 billion. In May 2017, Caltrain and the Federal Transit Administration (FTA) signed a USD647 million Full Funding Grant Agreement. In 2020, the US Congress appropriated USD472.96 million for the project. Caltrain has announced plans to develop a funding plan in 2021 in coordination with the project funding partners.


The scope of works includes electrification of an 82-km corridor from San Francisco’s 4th and King Caltrain Station to the Tamien Caltrain Station, and replacement of 75 per cent of Caltrain’s diesel service with electric service. The project also includes the design and purchase of 96 Electric Multiple Units (EMUs) the installation of an overhead contact system, and the construction of traction power substations.
