Uses an interesting and unique power system; SIDE-contact high-voltage third rail (1.2kV DC). The only other side-contact system like this I know of was the old Manchester to Bury line in Britain, electrified at the same voltage from 1916 to 1991 without issue, and only removed to be replaced with an integrated tram system. Curious why you don't see more, since it seems as rugged and speed-capable as top-contact and even easier to insulate than bottom-contact, also avoiding ice forming on the top (or icicles forming on the bottom) of the rail, and avoiding debris potentially getting lodged in the contact space. also seems to be safely able to operate at high voltage, for greater transmission efficiency, and better hill performance and acceleration. Really seems to be the best of both worlds; are there any glaring flaws i'm missing here?
@@alpzepta Regional trains typically connect between wide regions, think Amtrak's Northeast Corridor. People don't usually commute to work and back on these lines, though some do, perhaps on a more weekly basis. Commuter trains, on the other hand, serve far smaller locales, typically a city and its surrounding suburbs. Good examples of commuter trains are the trains people take daily for work, think JR East's Chuo Line. Many Railway companies don't distinguish commuter and regional trains, so some might grow up thinking they're the same thing. In this case Germany gives a clear distinction between the Hamburg S-Bahn and DB's actual regional rail service (InterRegio, Regionalbahn, Regional-Express, etc.)

The S-Bahn is no regional train alright. It's a commuter type train. Connecting within the city and surrounding areas.
vultschlange I agree, but Hamburg is a region, so maybe that’s why he called it that
vultschlange what a different between Reginal and Commuter train anyway?
