Are they radial bogies ?
They mechanically look like the SD70ACe bogies, which I'm fond of but know little about.
Whopping clearance under the fuel tank, doesn't look normal, although the 2800 has a good deal of it. I realise it needs to clear the railhead when it falls off.
The bogies are said to have radial steering capability.
I think the fuel capacity is limited to keep the weight down to 120 tonnes.
This is just my impression but they might be planning a heavier standard gauge version with the 20V4000 R53 engine....
