Munich/Alpharetta, November 21, 2019 – Kiepe Electric, a subsidiary of Knorr-Bremse, the global market leader for braking systems and a leading supplier of other rail and commercial vehicle subsystems, celebrates the delivery of 278 electric buses for San Francisco. The buses, manufactured by New Flyer in Crookston, Minnesota, are equipped with In Motion Charging Technology (IMC) of Kiepe Electric. The local transit agency in San Francisco (SFMTA) operates the largest fleet of zero emission electric trolley buses in the USA.

"The city of San Francisco is committed to operate an all-electric bus fleet by 2035 and we are proud to be part of this groundbreaking plan with our In Motion Charging technology", says Klaus Peter Canavan, Managing Director of Kiepe Electric in Alpharetta, GA.

"This is the last piece of a really comprehensive program to improve our vehicle fleet," said Julie Kirschbaum, Director of Transit SFMA. Kirschbaum appreciates the advantages of the new bus generation, the stronger batteries and the operational reliability on the daily on regular-service routes.

One of the largest US-orders of zero emission transit buses

New Flyer and Kiepe Electric have been awarded a contract to supply 278 electric buses with In Motion Charging. On November 21, 2019, New Flyer and Kiepe Electric, together with SFMTA celebrate the latest addition to one of the largest orders of zero emission transit buses in the USA. Muni’s 93 new articulated 90-foot electric buses with In Motion Charging technology have been a common sight in San Francisco since 2015. Now they are joined by their shorter siblings: 185 new 40-foot electric trolley buses are operating all over the City. 

The new electric buses are equipped with In Motion Charging Technology (IMC) from Kiepe Electric. The vehicles have powerful batteries that are charged while the bus is in motion and allow off-wire operation for several miles at a time. With this technology, buses can operate all day and do not need to be parked while the batteries are being charged.

Higher passenger comfort convinces the commuters in San Francisco. They notice the improved ride onboard SFMTA’s new electric buses. Low floors entrances offer easy access and the powerful electric motors hardly make a noise when powering the buses up the famous steep hills of San Francisco. For operation on steep inclines, a new Kiepe traction control (KTC) software was developed. KTC implies plenty of innovations and additional customer benefits such as less energy consumption, faster acceleration even on slippery roads and a reduction of noise and vibration resulting in less wear and maintenance costs.
