As indicated in a previous issue of this newsletter, because the SFMTA deploys one and two-car trains in the Market Street subway instead of the four and five-car trains the multi-billion dollar facility was designed to accommodate, the subway and adjoining Muni Metro tunnels currently operate at less than half their peak- period carrying capacity. This unhappy situation was caused in the mid-1990’s by a breathtakingly short-sighted decision to stop forming four and five-car trains.
Various reasons are cited for this enormously-consequential mistake, including pressure from the TWU (Muni operator’s union), coupling difficulties, maintenance problems, etc. but the most likely reason is that for reasons unknown, beginning in 1991 the then incoming Breda LRVs were arriving in San Francisco without the ability to couple LRVs together while in revenue service. Having reached the end of their useful life, the Breda’s are now being gradually replaced with new Siemens S200 LRVs, which began arriving in San Francisco in 2017.
In an effort to receive assurance that the Siemens car would at last allow the SFMTA to again begin using its subway effectively, Save Muni (www.savemuni.org), a San Francisco-based transit-advocacy group, sent several requests for information to the SFMTA during last August and September, followed up by a California Public Records Act/San Francisco Sunshine Ordinance request sent on November 5, 2019 asking for:
“1) All records from the past three years related to when the Muni Metro may be able to accommodate longer than two car trains
2) All records from the past three years related to tests of longer than two car trains in the ACTS territory, whether conducted by the MTA or outside contractors.”
