Re: Re: Sydney Metro

It will be interesting to see what they do then if they stick to the Alstom
product when they want the next series to run up to 130 km/h. The Perth A
series has a design speed of 120 and runs up to 110. The B (and future C)
series have a design speed of 160 and run up to 130, without sacrificing
good acceleration ability.
