How Many Motorized Road Vehicles Are There?

A List of Tomica World Motorized Vehicles
with some notes that may be of interest.
Part 1.

Nineteen different Tomica motorized vehicles were issued outside Japan under the Tomica World brand. Twelve of the nineteen were sold as individual items in blister packs with four-digit reference numbers in the 74nn and 75nn series. Of these twelve, four were also included in road/rail sets. The remaining seven were only available as part of a road/rail set.

Each different model of motorized vehicle has a TW number and a name printed on the underside. In some cases the name printed on the vehicle is different from the name on the blister pack, for example the red Nissan 300ZX has TW-06 NISSAN printed on the vehicle, but on the packaging it is 7475 SPORTS CAR (as well as equivalents in French, Dutch, German, Italian and Spanish).
 

Tomica World existed as a brand between 1998 and 2002. All the Tomica World vehicles are versions of the Tomica B series (B/O Tomica 1993-96) or A series (Motor Tomica 1997-99), re-labeled, re-numbered, and in some cases re-decorated for the international market.

TW-01 POLICE CAR(E), Ref.No. 7478, is a Nissan ZX300 based on the Nissan Fairlady Z Patrol Car B-02 (フェアレディZ パトロールカー), 1993.
 

TW-01 is also included in three sets: 7420 Basic Set, 7426 Super Set, and 7431 Basic Set (revised version).
 

TW-02 POLICE CAR(A) was only sold as part of U.S. Patrol Set 7414. It’s a Nissan ZX300 based on the Nissan Fairlady Z Patrol Car B-02(フェアレディZ パトロールカー), 1993.
 

I’m speculating that the (E) in TW-01 and the (A) in TW-02 stand for Europe and America respectively, since TW-01 is a British police car, and TW-02 is a US patrol car.

TW-03 ZOO-BUS was only sold as part of Large Set 7421. It’s based on the Amusement Park Bus A-06 (遊園地バス), 1997, but with different animals. The earlier B-14 had white wheels.
 

TW-04 TOYOTA TOWNACE was only sold as part of Mega Set 7422, and appears to be the same as the Toyota TownAce Noah A-12 (トヨタ タウンエースノア), 1997.
