Airport train with heavy bags requires strategy.

From central Paris: Board cars 3-5 for best elevator access at CDG Terminal 1-3 station. Cars 1-2 get packed with passengers going to Terminal 2.

From CDG: Exit towards Terminal 1-3 even if you came from Terminal 2. Shorter walk to RER platform and fewer stairs.

Luggage racks: Available but limited. Board early at Châtelet-Les Halles or Gare du Nord. Peak times (7-9am, 5-7pm) are brutal with bags.

Alternative: RER D to Châtelet then transfer to line 14 if your hotel is on that line. One less transfer with luggage.

Time: 45 minutes CDG to central Paris, add 15 minutes for transfers. Buy tickets in advance — €11.45 one way.
