As we all know by now, the upcoming Circle Line will also use Alstom Metropolis train cars similar to those currently found on the North-East line. I wonder though, apart from some minor aethestical differences, being powered by a third rail, and having only three cars,will the trains use a different propulsion system?
It seems like newer Alstom trains are using a propulsion system that are quite different from the ones on the North-East line currently; the Warsaw Metro in Poland, and the Washington Metro and New York City Subway in the U.S. all currently use Alstom trains with this propulsion system; note the same dinstinctive multi-pitch whistles these trains make. I'm wondering if the Circle Line trains will also have this propulsion system.
I not too sure if this is what you are refering to:
The NEL uses the Alstom ONIX traction system, and similarly, the CCL trains will also be using the ONIX traction system as can be found on this ppt: http://www.unife.org/uploads/070711_Alstom_Bell_Managing_Turnkey_Projects_CCL%20Singapore_Warsaw_RBF_UNIFE_Part1.ppt

I think it will be similar to the ones in New York etc, ie the "Violin" Alstom (as dubbed by some American Subway fans) sound, since they have 750V systems.
