@flomonster @clarani @Khoyo thanks for the review :) I've submitted an amendment to this proposal, which changes how margins and arrival times are defined: #164

Note meeting with PO (Alex + Giuliana)

• Are engineering margins useful (can be defined by scheduled points)?
  • If not, we can get rid of it.
• We need the standard margin system whatsoever. It compromises the suggestion here: design-docs: timetable: unify arrival times and margin types #164

Great!
