Old commercial of Bridgestone tires - feat. Sapporo Subway 2000 series

[Socimi]

Bridgestone produces tires for Sapporo Subway, the first and only rubber-tired metro in Japan.

 

This nice 1971 commercial shows the Bridgestone tires mounted on sapporo subway 2000 series trains, with some nice special effects.

 

 

Also note the unusual wheel arrangment of the DM (single wheel at the front, double at the middle, one between coaches) and the unique track arrangment: single central guiding rail, plus the   ̶t̶h̶i̶r̶d̶ second live rail in the middle of the two tracks (or shuold i say "lanes"?).

Also note the unusual wheel arrangment of the DM 

It's a 1-B-1-B-1 articulated arrangement with 2 fixed 2 axle bogies under each car and 3 pony trucks (one shared). This was first abandoned for the more conventional 3 bogies articulated ( B-B-B ) and later the two bogies solo car arrangement seen on most conventional steel wheeled multiple units.
