Motorising older trains using Power Functions

We introduced LEGO® Power Functions in 2009 as the new electric building system to replace the 9V, 12V and RC systems. What’s great about Power Functions is that they can still power your favourite trains from years ago!

You might have to make some slight changes to the design to fit the Power Functions elements, but here’s what you’ll need to get you trains updated:
 

• Either 88000 LEGO® Power Functions AAA Battery Box or 8878 LEGO® Power Functions Rechargeable Battery Box and 45517 Transformer 10V DC
• 8884 LEGO® Power Functions IR Receiver
• 8879 LEGO® Power Functions IR Speed Remote Control
• 88002 LEGO® Power Functions Train Motor with 8886 LEGO® Power Functions Extension Wire
