What would you do if a big event was happening in a map?

[NJTFAN1235!]

Okay, so I wanted to ask, if there's a big event or marathon happening in a map, what would you do?

For me? I would pick Rijndam 2018

Event: Kings Day (IDK the dutch name for it),
Possible idea for me:
M3: Increase M3 service to have both via Garenmarkt & via Nationale Opera.
M2: Nothing as there's a lot of trains on M3.
M4: Add service on M4 to operate to Westplein when required.
M1: TBH, It's kinda big line and it has many possible destinations: Noordvliet, Panbos, Noorderpoort, Westpoort (if you can port the timetable from Rijndam2020, it will still work, just replace W with J). I would pick a destination that is not operated by M1.
M5: I probably do not know, it's a small line so....... Moving on....
Rijndam Rail: Add more frequencies!!!!!
