Hey, if Alstom can flog these clowns a product that locks TfNSW into a single supplier for the foreseeable future why shouldn’t CAF have a go?
And they managed to sell two different charging systems for Newcastle and Parramatta - as PT Barnum said, “never give a sucker an even break”.

It stands to reason that you can't use the technology on hills and this section of the Parramatta line is on rising ground either side of the Parramatta River basin that it crosses. Even trolleybus systems, where the technology originated, wire any hill sections, not only for climbing, but for regenerative downhill braking as well. It's about a 30 metre rise from the river to the Hawkesbury Road terminus.Tony POn Friday 23 August 2024 at 10:50:48 UTC+10 Matthew Geier wrote:On 22/8/24 22:25, Tony Galloway wrote:

Probably found the batteries are not quite up to running up the hill to
Westmead. I guess they will have to turn the air-conditioning off at
Ngara to save power for the climb up to Westmead. :-)
Still can't fathom why Hawksbury road doesn't have overhead - not as if
there is any classic architecture that would be 'visually ruined' by
overhead and extra poles to hold it. CAF just wanted to show off and
find an excuse to sell TfNSW a proprietary ground charger.--
