Montreal Metro: AZUR
The shiny new rolling stock of the Montreal Metro, built by a joint venture between Bombardier & Alstom. Featuring open gangways, smoother rides & colorful LED lights. They do retain the wooden brake shoes from the older rolling stock though. Resembles the MP89 in Paris in some aspects. 加減速有悲鳴の音
The AZUR is the longest rubber-tyred EMU I know of, with each unit at 152.43 m. Other high capacity systems with rubber tyres around the world (eg Paris, Sapporo, Mexico City) have shorter trains. Do correct me if I'm wrong :)
