The train would therefore accelerate at a certain rate until halfway, and then decelerate until it reached its destination.

What would be the travelling time of such a train as a function of the distance?

where t is the time, s is the distance and g is the accelleration.

Calculated using the fact that distance travelled is the area underneath a velocity-time graph.

What acceleration value g should I use? I'm looking for an acceleration/deceleration that is hardly noticeable for the passengers, making the journey comfortable.

The chairs could turn 180 degrees when the train is going to decelerate. The top speed would be 2.7km/s.

The usual problem with trains is that they start and stop at all the intermediate stations...

At the distance x the train is accelerated until x/2 so the time is expressed as:

x/2=gt²/2

t=√x/g
