In my city, they wanted to reduce the amount of money spent on overtime for transit operators.
The biggest source of overtime, was not getting operators back to their clock-out point on time for the shift end. Like, a bus driver behind on their schedule, and arriving late at the depot. Or a subway operator being on the opposite end of the city, and needing to get back to where they parked their car.
The transit agency decided the best way to address this was... setting drop-dead deadlines for operators to stop driving the route and return to clock-out. For buses, this meant "kick everyone off the bus, go to depot NOW." For subways, this either meant, "kick everyone off the train, turn it back into the direction of the operator's clock out point," or, "stop the train, wait for an opposite direction train, swap the crews."
Where this intersects with nighttime transit, is that nighttime is where a lot of those shift change problems are happening. The number of vehicles being operated is tapering down, so you need operators to wrap up on time. But, also, the number of vehicles being operated is going down, so any kind of disruption to the schedule means it will be as much as 30 minutes until the next scheduled vehicle.
Overnight transit was hellish before I just started biking literally everywhere, no matter the distance.
