BROOKLYN - The next generation of subway cars are in the works for city straphangers.

The chairman and president of the MTA traveled upstate to Plattsburgh Wednesday to visit the manufacturing site for Bombardier Transportation where 300 of the R-179 cars are being produced.

The new design is similar to the current R-160 cars on the tracks today, but commuters can expect brighter lights, improved heating and air conditioning, and digital voice announcements.

Officials say the trains are only scheduled for the lettered lines, including the B and D, and will arrive by 2015.
