Re: Trackless trams for Melbourne

The CAF AXL for Stockholm is partly high floor - over the end (swivelling)
bogies. To get the shorter length they would use only the two end modules
with cabs and I imagine put a bogie under the other end of one module to
support the tram in the middle. CAF doesn't have much experience with this
type of tram. I presume UGL's involvement is to make local assembly
possible. The batteries don't make sense (except for emergency propulsion)
when the whole system is covered by wires. It's almost like they have to
have the latest environmental fashion accessory, even when it's not
particularly environmental.
