~New Transit Fleet Order from LA and San Diego Largest Ever in North America~ 

VANCOUVER, Feb. 5, 2013 /PRNewswire/ - Cummins Westport Inc. (CWI), a  leading 
provider of high-performance, alternative fuel engines for the North  American 
on-highway market, is  supplying engines for  two of the  largest natural  gas 
transit fleet orders in North America to date.

In January,  LA Metro  announced its  plans to  order 550  New Flyer  Xcelsior 
natural gas buses, powered with the Cummins Westport ISL G 8.9 litre engine to
be deployed in 2014  and 2015, with  an option to  purchase an additional  350 
buses in 2016 for both its own fleet and contract operators. LA Metro has  one 
of the largest transit fleets in North America.

"We have had  a good working  relationship with Cummins  Westport," said  John 
Drayton, Manager for  Vehicle Technology for  LA Metro. "There  are more  than 
1,500 natural gas  buses in  our fleet  running on  CWI engines.  LA Metro  is 
dedicated to being 100  percent natural gas,  and CWI is  a valued partner  in 
that."

In December 2012, the San Diego Metropolitan Transit System (SDMTS)  announced 
the decision to purchase up to 350 Gillig 40-foot low floor buses and 118  New 
Flyer 60-foot low  floor articulated  buses, all powered  with the  CWI ISL  G 
8.9L. SDMTS will receive 47 articulated buses and 50 forty-foot buses in 2013,
with another  50 per  year being  delivered to  replace buses  in the  current 
compressed natural gas (CNG) fueled fleet over the following four years.

"San Diego's transit system has been on the path of natural gas transportation
for a long time, and our fleet  is composed of 80 percent CNG vehicles,"  said 
Julio Ortiz, Director of Maintenance with  SDMTS. "We have always been a  good 
customer of CWI."

Currently, there are more than 7,000  buses in municipal service across  North 
America fueled by natural gas.

"Substantial orders such  as these  from LA Metro  and San  Diego are  ongoing 
evidence of the growing acceptance of natural gas in the transit market," said
Jim Arthurs, President, Cummins Westport.
