Comments on: Two Muni Light Rail Vehicles Collide at West Portal Station http://sf.streetsblog.org/2009/07/18/two-muni-light-rail-vehicles-collide-at-west-portal-station/ Covering San Francisco's livable streets movement Tue, 07 Feb 2012 16:15:00 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Jeffrey W.

It's within the realm of possibility that the event was caused by the automatic control system, not the lack of one. Or quite possibly due to the front train having cut out the ATCS, making the rear train think the platform was clear. In any case it will probably be many weeks before Muni announces their findings.

How this accident compares with the other similar accident in the West Portal tunnel a few years ago, knocked out service for a long time while they rebuilt the rails. 2. How this accident, once the cause is unraveled, may have been mitigated by automated equipment, perhaps like the sort used on BART trains. Two information requests:
