The train destroyed that Fiat... But what kind of train is this? It looks like it has tires on it....
Edit: I did some research, and it's called a rubber-tyred metro. Interesting; I've never heard of this.

Mexico City, Montreal, and I think Paris use the same system. It's quieter, but less efficient.

Probably, since the Mexico City Metro was built by the French company that built the Paris Metro. Later on they built a plant in Mexico and now it´s all done here, but they´re essentially the same Metro. Don´t know about Montreal.

Quoting lewis (Reply 5): Line 1 in Paris has it, a very quiet and smooth ride without metal screeching.
Lines 1, 4, 6 and 14 in Paris have it, if I'm not mistaken. The others are conventional steel-on-steel (which is heck of a lot simpler - four wheels per bogie rather than 12).

These, and line 11 as well. The French pioneered the technology back in the 1950s (line 11 was the first to be converted) and then they applied it to some of their other lines and they helped export it to Mexico etc.

Quoting signol (Reply 8): Rubber types give faster acceleration but lower top speed, so better if the stations are close together.
Also higher rolling friction, but much quieter. Maintenance is required more often (tire changes) but is easier and less costly to do than replacing steel wheels. On balance, steel-on-steel has won the contest in almost every case.
Oh... SFO's Airtrain uses rubber tires, too. JFK's uses steel-on-steel, but that system uses direct linear drive.
