Just a random thought.An EMU Comet car? The OG MLs were double decker adaptations of Comet Vs. They should make Comet VI cars, there are a number of services and lines that don't need double deckers and would be better served with slightly longer trains of Comet VI.

I could perhaps see the Silverliner Vs lasting until that time frame. However, the IVs are like 47 years old. Presently, Septa is looking into replacing them down the road.Anything can be made to last as long as the frame isn't cracked or otherwise failing. It just depends on how uneconomical it is to keep rebuilding stuff. Diesel road switchers apparently can be rebuilt almost infinitely, they are rebuilding units from the 1950's.
