Probably the "oldest" equipment I can think of is Philidephia's streetcars, which are over 80. They will likely be past a century before they are retired.
There probably isn't an original part left on any of those streetcars, but I think it appropriately shows how long equipment can last when you do a complete rebuild and constant maintenance.
what about the cable cars in San Francisco?
