The DTX project will extend the 78-mile existing Caltrain the last 1.3 miles into the Salesforce Transit Center in downtown San Francisco. While the downtown is no longer the employment center it used to be, Salesforce remains a major nexus of local and regional transit systems which, when Caltrain is extended, will connect 11 passenger rail lines and over 40 bus lines.

Extracted from the just released SFCTA staff’s 41-page report to its CAC and Board:
The total estimated cost of the project, with the already built $729 million train box included, currently stands at $8,280 billion in Year of Expenditure dollars. According to the SFCTA report, a federal FTC grant of $4.1 billion is expected to cover 49.5% of this amount, leaving $4.18 billion to be paid from other federal sources as well as from State of California, regional, local and private sources. Of the $4.18 billion, $1.9 billion is already fully committed to the project. Here’s the breakdown of the anticipated funding.

According to the SFCTA’s schedule, construction will begin late in 2025, with Caltrain revenue service at Salesforce scheduled to begin by mid-2032.

This has been dragging on for a century. First the SP g4neral office building, now One Market Street, was going to double as SF’s train station. then, 40 years ago, Caltrain actually showed three peak trains serving downtown using State Belt tracks while planning to extend its service to the Rincon Annex post office. Forgive me for not getting excited about DTX.

A century ago things were different. Since then four BART lines, six Muni subway lines have been built. Those ten lines plus the old time streetcars on Market plus the California cable car line plus Caltrain totals 13 passenger rail lines all coming together at or very close to the Salesforce Transit Center. And over 40 bus lines.
People talk of seamless transit. This would be the most important example of seamless transit west of NYC. Yes it’s too expensive but it’s all we got.

My point was that there has been talk for a century about bringing SP/Caltrain closer to downtown Ess Eff and nothing ever happens. I don’t think it ever will.

Extending SP/Caltrain to downtown has been under discussion for over a century. The SP office building, now One Market Street, was designed to function as a train station.
40 years ago, in the early Caltrain era, three peak hour trains were projected to serve downtown via State Belt tracks while they studied using the Rincon Annex Post Office.
Excuse me for not getting excited about DTX.
