Woodstock, BHP Billiton SD70ACe locomotive 4327 was built by Electro-Motive as an EMD model SD70ACe for the BNSF railroad in the USA with serial 20066862-056 but was sold to BHP while under construction as one of ten similar units to be diverted to BHP in an all over BNSF base orange earning them the nickname of 'pumpkins' after the BNSF livery. They were standard US domestic units and required substantial modifications to be afforded lead unit status for BHP. Here we some a couple of the modifications like the snow plough and the middle handrail and the windscreen protector is just visible. 14th August 2009.
