The second series of Bandai's Thomas Town series was released in 2000 and included the first non-engine rolling stock in the series. I don't have the track sections to this series but I do have a set of correctly-dated engines. An archived copy of an old Japanese fansite that shows the series with its track can be found here.
The Friendly Thomas set in this series included a small truck. The track piece for this section included a barn with a cow that could be slid in and out.
The truck is neat and has stickers on the ends. Because the rolling stock was considered an accessory really, the roller wheel colors match the other pieces on the sprew.
Thomas Town 2 Oliver included a curve rail section with a rock piece and signal.
Friendly Stepney originally included a T section with a passenger crossing bridge and a tunnel.
Gordon originally included a track section with a station and a turntable at the end.
Thomas Town 2 Duck, who originally came with a rather neat looking harbor piece with a crane and a barge...
I do have a few pieces from this series...
