What are good majors to look at for high speed trians?
The new California high speed rail system was passed recently. I grew up in a family who always been around trains.But I was wondering what engineering jobs are associated with anything and everything that has to do with the high speed rail.What majors are good to look at in collegeThank you
Mechanical Engineering for the engines, Chem E for fuel cell stuff, and probably civil engineer for general design work.

Hi, JT here. Thanks for visiting my Drag Race Car site. Hope you find what you're looking for...there's tons of information and links here. Feel free to leave comments or drop me a line.
Ohio's rejection of high-speed rails benefits Florida, 13 other states: Ohio Governor-elect Kasich said thanks b…
Yeah, it's about time.
California is proposing a high-speed train from LA to SF… vote for it in November!
Let the car’s initial velocity be w.
Initial momentum = {M +2m} w.
Final momentum = M v + mu -mu = Mv.
Mv = {M +2m} w
v = {M +2m} w / M.
