Does any of Schools in US run a Part time transportation Design Course (one which you can learn on week ends / evenings ) ?

definitely!
art center provides night courses at art center at night program...

http://www.artcenter.edu/atnight/main.jsp

thats their website.
it's run by art center, helping students prepare and shape a strong portfolio prior to getting into the actual art center school.

good luck!

p.s; keep in mind though, this isn't a degree program, it's just one of those neat things where anyone can come in and learn to develop their portfolio...
