Are overnight trains always tiring?

Not always. Timing, useful sleep opportunity, seat or sleeper type, crowding and personal sleep ability change the result.

Train fatigue calculator

How tiring will these hours on the train feel?

Estimate the effect of duration, overnight timing, seating, occupancy and your ability to sleep.

A nine-hour daytime journey in a reserved first-class seat can be easier than six overnight hours upright in a full carriage. This quick tool isolates that fatigue question; the full model adds transfers and station effort.
