Siemens SD100 Light Rail Vehicle

Vehicle Number & Year of Production

2001-2050 (1993-1996) 2051-2052 (1998)

The original second generation of Light Rail Vehicles (LRV's) purchased by San Diego Trolley for the Orange Line expansion to Santee in 1995 and the Mission Valley West alignment shortly thereafter. Now, the SD100s can now be found on all three lines. These cars are easily distinguishable by their large single "trapezoid shaped" windshield and their "box car" shaped design. Many have been recently repainted, taking on the appearance of newly manufactured LRVs. These units are compatible with the newer S70-series LRV's and are frequently used as the middle car in an S70-SD100-S70 "mixed" consist.
