The purchase of Muni’s next metro train fleet took a major step forward today as the SFMTA Board of Directors unanimously approved a manufacturing contract with Siemens.
Muni officials lauded the design of the new trains as far superior to the current, abysmally breakdown-prone fleet of light-rail vehicles, which were built by AnsaldoBreda. The fleet of 260 new trains will be manufactured by the German company Siemens at its Sacramento factory, and will roll out in phases starting at the end of 2016.
The contract approval “will put us on a structured, long-term course to take care of our most immediate and pressing service need right now — to fix the very heart of our transit service network,” said Muni Operations Director John Haley.
Muni metro riders can expect breakdowns to become much less common with the new fleet. The current Breda trains have a “mean distance between failure” rate of fewer than 5,000 miles, according to Haley, which means that they break down routinely. A city audit painted an even more dire picture, finding that Muni metro’s aging trains break down every 617 miles on average — far more often than any comparable transit system.
The Siemens trains have proven to break down every 59,000 miles in service elsewhere, more than double the minimum of 25,000 that Muni officials had set as a minimum for qualifying contract bidders. It’s also “more than twice around the equator,” said Haley.
As an example of the improvement of what Haley has called Breda’s “high-failure design,” the current trains have over 220 moving parts in the doors and raising steps alone. The Siemens trains have 20, Haley said.
