Foam patches the window; Glass fixes the lamp
Use Foam to patch the damaged train window that is leaking air. The carriage lamp is a separate repair that needs Glass, so keep those two train jobs distinct.
Collect Foam and restore the window insulation
- Look for the old fridge-like object with cuttable Foam. Cut the Foam from that object and collect it for the patch.
- Bring the Foam back to the train and use it as a patch on the damaged window.
- Add the Teddy Bear to the window's insulation setup to improve the train's warmth.
- Collect Glass separately when replacing the carriage lamp. Glass also goes into the Flashlight after its recipe becomes available.
Choosing the right train-repair material
- Which train repair uses Glass rather than the Foam patch?
- Replacing the lamp inside the carriage requires Glass. Use Foam for the window patch and the Teddy Bear for its additional insulation.
