But what about on national rail services, which have manual door operations?
People seem to use them just fine. Same goes for the DLR and Croydon
Tramlink.

Having them is good, particularly in the winter, because it conserves
energy.

I notice that many undergrounds in continental Europe have manual door
opening, and nobody blinks an eye at it.

But newer stock on the Paris Metro has only driver-controlled doors, which
is a departure from the older models, where you had to lift a latch.

I've been trying to find evidence for this unsuccessfully, but I think I
once heard that the passenger door control is not normally used because it
slows the service down, because opening the doors takes longer at
stations. Individuals randomly positioned on the platform aren't lined up
with the doors, and aren't as fast as the driver, who knows exactly 'when'
to operate them...
