What I can identified in the video:

- point at speedometer to confirm current speed

- point at master control (acceleration control) to confirm zero (likely during dead sections)

- point at clock and timetable to confirm arrival/passing time

The painting at the end is likely to confirm activation of auto-breaking of ATC train control system.

IIRC they monitor arrival and departure at various levels and times. Speed levels, braking, location @ time, etc. In the video she says "yosh" / "yoshi" after each which is like "(X) is good"
