As for questions 4 and 7, the maximum weight of 'heavy rail' trains is mainly limited by the strength of their coupling systems and the rails on which they ride. European 'buffer and chain' coupled freight trains are limited to about 750m in length and about 3000t in weight, this due to that relatively weak coupling standard. OTOH, trains on Russian 'broad' gauge lines and those on standard-gauge lines using AAR 'Type E' couplers (mainly used in North America, China and Australia, plus a few other places) can be far longer and heavier - this due to their much stronger couplers. The coupling standard used on Russian broad-gauge lines is about six times stronger than 'buffer and chain' and AAR 'Type E' couplers have about eight times the strength of 'buffer and chain'. 14.000t trains hauled solely by locomotives at the front are everyday things here in North America (IIRC, the theoretical maximum weight for trains with 'Type E' couplers is in the 25.000-30.000t range). With locomotives added elsewhere in the train, its length and weight can be greatly increased from those other limits.i love trains.
unfortunately, i live in a country where the train system...is no good.
it brings many questions to mind...
1.what is the difference between light and heavy rail?
2.what speeds do these usually achieve?
3.how fast do they accelarate?
4.how much heavier are heavy rail trains?
5. does this make them more dangerous?
6.does all the wheel sets onboard have brakes?
7. if all of the wheel sets onboard have brakes, how come length is limited?
8. can light rail serve intercity 200 km long lines?
hope you still have the energy to write...:nuts:
have a good day!
Train lengths are also limited by lengths of passing sidings and yard tracks and weights can also be limited by the maximum ratings of electrical power supply systems on electrified lines.
The normal maximum freight car axle loading here in North America is about 30t.
I hope that this helps.
Yes, it is a little bit heavier than what runs in Israel.
