It is possible, but not convenient.
Option 1: buy a Carrera 1:43 terminal track and transformer, and add it to this set. Good luck finding one on its own. I did a few searches and didn't find any. If you have a shop locally that stocks slot car kits, cars accessories, they can help. But, those are few and far between.
Option 2, buy a Carrera Go!! 1:43 set that has an AC transformer, and use that terminal and transformer with this track. But, why not just buy a bigger set to start with? Oh, cost.
Bigger set at Amazon
This is a good deal if you will be satisfied with a small track, and are OK with D-cells.
If you already have Carrera 1:43 track, and want the TMNT trikes to add to your collection, then this is a GREAT DEAL! They can be found for $15.99 each, and you get some additional track to go with it.
