I noticed that as well, especially considering that the Moscow City Government is seriously considering dismantling a part of it. Let's not forget about Sydney. And North Haverbrook. |

Doesn't make much difference really A good part of the weight will the running gear wheels, motors and the bogie frames They will be supported direct by the wheels on top of the rail just like an ordinary train though the rail will have to be strong enough for 100% of the weight rather than 50%. The suspension arms and the body work which hang below will be relatively light in comparison to the mechanicals. Quick google, Found this which is a fansite http://www.schwebebahn-in-wuppertal.de/neuezuegee.htm The figures don't add up to 25 tonnes though, two bogies at 12.5 Tonnes does , then bodies at 5.4 Tonnes so a car 30.5 in total. Wonder which is the more accurate figure, anyhow looking at the specs for the older cars the ratio of running gear to body work weight seems to be similar . G.Harman Interesting - thanks. Next question - I'm surprised the inside of the vehicles isn't more symmetrical... |
