  <p>The wheel axles are fixed to one point so they cannot navigate curved pieces of track easily. A simple modification should be able to fix this. </p>

Answers.Body: <p>The wheel used are smaller than regular train wheels and are usually never used in train sets; but more for smaller train-like stuff (<a href="http://www.brickset.com/detail/?set=4855-1" rel="nofollow">Spider-Man metro</a>, <a href="http://www.brickset.com/detail/?Set=7199-1" rel="nofollow">Indiana Jones mine cart</a>, <a href="http://www.brickset.com/detail/?Set=2585-1" rel="nofollow">track buggy</a>, <a href="http://www.brickset.com/detail/?Set=7936-1" rel="nofollow">track maintenance vehicles</a>...)</p>
  
  <p>So they will work on regular track, but their smaller size mean they're more likely to derail, and they have more friction around the axle than normal train wheels. Straight track is definitely OK, curves will presumably be good too, but be careful around switches. </p>

  (Asked by: username_0 on 2011-10-29)
  
  Among other things, set [8404](http://brickset.com/sets/8404-1) contains a train but it doesn't come with any track pieces (see set [7499](http://brickset.com/sets/7499-1)). Is this train compatible with these Lego City tracks? I see where it's more of an electric trolly and if it's not track compatible, is it at least wheeled?

  It uses train wheels which means it should work on Lego track.

  So they will work on regular track, but their smaller size mean they're more likely to derail, and they have more friction around the axle than normal train wheels. Straight track is definitely OK, curves will presumably be good too, but be careful around switches.
