With the right amount of inventment, they really could make these the last trains that WDW will need to purchase. Not say that the can litterall last forever but honestly, if you can get 100 year old steam engines still working effectively, there is no reason you can't double or triple the life expectancy to 40 or 60 years for monorail.
It gets to the point where its no longer viable to do that though.
Use larger systems as an example. The London Underground for example. Trains typically are in operation for upto 50 years, and even after that have continued to be used elsewhere (e.g the 1938 stock, many of which was actually refurbished 1927 stock) are still in use on the Isle of Wight today. That's an 80 year old electric train still in use!
That being said, over time you end up replacing so many parts that it becomes a new vehicle. The issue Disney has here is that the body of their monorail trains is fibreglass, which doesnt stand up as well as the steel trains. The current fleet would cost tens of millions to overhaul, at which point its better to cut your losses and get a new fleet that is built to last (the current monorail was never built to last longer than 20 years).
A new fleet could certainly last 50 years. Anything more than that really becomes more effort than its worth.
