The ETI/Škoda Trolleybus era in San Francisco 1999-2019

Electric Transit, Inc. (ETI) was a joint venture between the Škoda group in the Czech Republic and AAI Corporation in the United States which made trolleybuses for Dayton and San Francisco (MUNI).

Two prototypes (numbers 5401-5402) for the two-axle trolleybuses (model 14TrSF) were received by MUNI in 1999, while an articulated (model 15TrSF) prototype (number 7101) was received in 2000. These models were specially derived from the Škoda 14Tr and 15Tr trolleybuses.

The 238 production-series two-axle trolleybuses (5403-5640) were delivered between 2001 and 2004. The articulateds (7102-7133) were delivered in 2003.

As they aged, they had a lot of mechanical failures. In 2013 it was decided to replace the whole trolleybus fleet with New Flyer XT40 and XT60 trolleybuses.

The last of the 15TrSF articulated trolleybuses were already retired in 2016. In September 2019 also the last 14TrSF were retired.
