International Railroad Discussion > Wabtech U.S battery powered unit for Vale mining (Brazil).

Vale released the project of its new battery powered unit to be built by Wabtech USA. MRS and Rumo will receive units for test too.  No data about the model was said. Any idea if it is the same model in test by some US railroads?

Very cool! That looks like a much higher KWHr capacity than the designs for CN and UP. Those have walkways on the side and are hood units. This one looks much closer to the SD70J-BB for Fortesque but using 6 instead of 8 axles.

Are they using dry batteries or the more dependable
lead acid batteries?

I wonder if the builders have installed permanent magnets
and slip rings on the axles to collect low voltage electricity
to feed back to the battery banks?

In saying the above perhaps a secondary high speed gearing
on each axle with a nested permanent magnets and collector rings
with carbon brushes on each axle would be what they used?     

The Wabtec 3000 is a nice looking unit, hope it test well.

Unfortunately I do not have the locomotive data to see these informations. I know that MRS rr ordered an hybrid diesel & battery unit to test in its heavy haul ore system. By the templates the company run along the system, it will be bigger and heavier than an ES44.

Definitely not lead acid.
