Western Railroad Discussion > MPEX 5000?

Saw this locomotive mpex 5000 come throught Waxhaw, NC about 520PM as trailing unit behind up 3837, up 9639. Trying to find out was type loco it is. Though it might be mk 5000 but it had flaired radiators like sd45 but had wide cab. If any knows thanks in advance.

MPEX 5000 is classified as an SD50-3. It was originally built as ATSF SD45 1881 and was later renumbered to ATSF 5581. The Santa Fe rebuilt the unit as cabless SD45B 5501:2. It was eventually acquired by Motive Power Industries and was rebuilt at their Boise Locomotive Works as an SD50-3 protoype with comfort cab. The unit was initially leased to Dakota Minnesota & Eastern and was painted and lettered as DM&E 5000. It was returned by DM&E to MPI and is now MPEX 5000.
