  Looking at the description in the specification for 10428 which states:
  
  > They can load the train with cargo, charge the engine or wash the carriages. Each activity is brought to life with lights and sounds when the toy train passes over one of the 5 action bricks.
  
  I imagine that they trigger different sounds from the engine, such as running water, zapping/charging or general clanking, based a little bit on the pictures and that description

They can also use the special customization brick to play their own sounds recorded using the free LEGO® DUPLO® Interactive Trains app, which also lets them drive the train using a portable electronic device.
  
  Again suggesting that the bricks will trigger specific sounds (birds/woodland, etc.) judging by the video on that page, the Red "House" brick acts as a Stop brick.
  
  I expect the older trains might pick up some of the bricks for example [this answer from Jan 2024](https://bricks.stackexchange.com/a/18472/56) notes that the sensor was cycling through a series of colours to find a match, so the more recent trains may well do something for some of the colours.
