As a person living in Osaka, Japan right now, I always find it funny reading people comment on NYC Subway. Not your specifically, but in general.
In Osaka, Hankyu Railway (granted, a commuter train operator, but most if not all commuter trains service in Japan runs like subway) still runs multiple 3300 series, manufactured in 1969. They (the 3300's) actually also run into the Osaka Metro system, and you cannot really tell it's built almost 50 years ago.
And CTBC... Most of the newslet says that one of the problem with old system is that it cannot accurately tell where the train is... Well, I know NYC signalling system is ancient, but not being able to tell accurately where the train is IS NOT the problem. Most of the Japanese lines (including various subways) still run on block system (though sometime with a block length of just 100m). Communication-based system is in place on some line, though, but mostly for lightly-traffic line to save on signalling equipment cost.
Yea I figured this may be mentioned, it's the same in the UK they were running very old train stock of the same vintage until (I think) this year? I know it's also not the only problem but both the Japanese and UK cartridges aren't complete shit and falling apart.
Three times in the past 2 years (since I moved to the G line) the train had to be evacuated because the brakes locked on a car and someone smelled the awful burning it thinking it was an actual fire in the car. THREE TIMES.
If you maintain the cartridges there's no problem at all but there are so many problems it's way beyond that.
I'm a little of a train nerd (if not obvious) so I went to the train stock as an example but other underground systems prove that proper, well funded and well managed maintenance will make this a non-issue.
"Proper. Well Funded. Well Managed."
- Not the MTA Subway System
London's oldest trains are from 1972, the 1969 stuff was withdrawn by the end of 2014.
But England runs older trains, and this has recently been newsworthy [1]. I think the underlying problem is the electrification of two lines has been delayed, so the newer diesel trains used on those lines are still needed, and can't (as originally planned) be used to increase capacity on the other route.
It also shows that London's transport, which is directly managed by a government body, works far better than the privatized mess in the rest of the country.
