RW - You need to do some more research to get your rail car builder comments right...
Yes - The M8 and M9 cars were built by Kawasaki ("Let the Good Times Roll")...Remember Kawasaki motorcycles?
The Silverliner Five cars were built by Hyundai Rotem - which is based in Seoul, South Korea...

What SEPTA needs is a 180 to 200 car order of a new Silverliner Six fleet to replace the aging S4 MU car fleet that is
now 46-47-48 years old at this time (1974-75-76) that is still the backbone of the SEPTA RRD fleet. The new CRRC
multilevel cars will supplement the single level push-pull cars meaning that slightly less new MU cars would be
needed to replace 230 S4 cars. With SEPTA's mix of high and low level platforms the ability to serve both will be
necessary...MU cars offer more flexibility to SEPTA's electrified RRD system than locomotive (ACS-64) hauled
consists will especially on shorter branches with stations in close proximity to one another...MACTRAXX
