Stadler and Caltrain solidified their partnership with the signing of a Technical Support and Spare Supply Agreement (TSSSA), marking a significant step in ensuring the efficiency and material availability of Caltrain's growing fleet of electric multiple units (EMUs).
The agreement provides on-site technical support, maintenance management software implementation, full material management for both preventive and corrective maintenance, and diagnostic assistance.
TSSSA Details
Covering all current and future Stadler EMUs operated by Caltrain, the TSSSA underscores the commitment to delivering superior service for Bay Area commuters.
Under the TSSSA, Stadler will employ a dedicated team of 14 specialists based in California.
The team will support reliable operations and maximize the performance of Caltrain’s fleet, so customers have a safe and world-class experience. The contract also allows both parties to opt-in the future battery EMU pilot train into this agreement.
Building on an Existing Relationship
Caltrain’s partnership with Stadler began in 2017 with the order of 16 KISS electric train sets.
The order was later expanded to 23 train sets, and the majority of the fleet, built by and delivered from Stadler’s Salt Lake City location, began revenue service in September 2024.
“This agreement represents our shared commitment to availability and continuous improvement” said Rachelle Glazier, head of Stadler Rail Service US. “We are proud to continue our partnership with Caltrain and support their mission to provide clean, efficient, and sustainable transportation for the Bay Area.”
