i got one more set of pics of the Delhi Metro wheels....i will update this thread as i gather more pics/info and i request Mods to keep this thread alive in archives!...These wheels provide a service to thousands of daily commuters and preserve energy, and i say this , much as i love cars and all things car!!!...any govt. body or city that promotes and expends resources on mass transportation in any country should be commended and deserves mention!......
