MagLev Trains
Is it true that MagLev trains don't suffer from gradient problems? The reason I'm asking is that where I live they are planning to improve the road tunnel from a single road system to a dual road tunnel system.
Most of the public is against it, many - like myself - want to see a rail network under the River - but apparantly the gradient is too much for a convenetial light railway.

*starting all over again*
I haven't read too much about maglevs other than the webpages about those two projects going on. And afaik the tests have only been done on mostly flat terrain.
You still have to use more energy when traveling uphill, so I guess there is a physical limit for maglevs too.

Maglevs
Yes, I meant in real life not in TT. As far as I'm aware no Maglev is being proposed or built in the UK - but I read or mis-read that a Maglev doesn't suffer the same gradient problems in going up/down hill.
Never mind though, thanks for your help.

Dunno how it works for Japan project but I know something about the german one.
Basicly the maglev is driven by the linear electric motor - the train has the function of rotor and track is [the other thing of the elctric motor i don't know and couldn't find the name of]. There is no engine in such train.
When a gradient is met then more power is pumped into the track overcoming the gradient. Power varies of the train so velocity remains the same. Likewise in normal steel railorads power of the engine is more or less constant (exocluding steam engines) so when a gradient is reached then some power is needed to ovecrome it hence velocity must drop.
