There are two trucks under this engine and all wheels are driven by chains. Note - the chains are not loose to allow for turning; there are constant speed universal joints built into each truck to allow for turns.
I have hauled 11 preschool children, 11 adults and myself around the SVLS track with no problems. With beams working up and down while I run it is quite an attention getter.
