They wobble a little, but if the track is level and you're going in a circle
(not going straight part of the time) at a constant speed you may not get any
wobble at all. Cars that use two trucks (and thus sit on bogie plates
<part:4092> are going to wobble more than short cars that use directly connected
wheels.

Depends on how low the track is, but a single truck car, probably about 3 bricks
above the rail height, if you use standard wheels <part:2878>, a little less if
you use the tinypin small wheels <part:2927> that connect to the tinypin plate
<part:2926>. If you use the drop center bogie plate (which is a two truck
design) as in <set:4561> (follow the link to the peeron inventory to see that
the set includes this part <part:2972> or build your own drop center, you can
get quite a bit lower... probably more like about 1 brick above the rail height.

Yes there is a minimum/maximum circle diameter for curved tracks.
Was there something else? Oh, you want to know what it IS... it's the same in
both cases, the same diameter as there is only one track radius available. 40
studs to the track center, IIRC.

Hope that helps.

| But the wobble is realistic in a way. if you watch a slow moving train, rolling along, it sways side to side a little bit, this is because it is almost imppossible & un-needed to have the track PERFECTLY level, unless of course you're speaking of (...) (21 years ago, 12-Oct-03, to lugnet.trains)
