For Caltrain, 16 KISSes from Stadler (but no FLIRTs)
FLIRT—Flinker Leichter Innovativer Regional Triebzug, or “Fast Light Innovative Regional Train”—1,300 units of which have been sold in 17 countries. The KISS vehicle (the name is an acronym of the German for comfortable innovative speedy suburban train) is also very popular, as 242 trainsets comprising 1,145 cars have been sold in eight countries, nine with the Caltrain contract)
And another reference to the 150-year history of Caltrain !
“The Caltrain Modernization Program represents the single-most transformative project in Caltrain’s 150-year history,” said Jim Hartnett.
