After the 1970s energy crisis the Fenix Pacific decided to electrify from Greenville NC to Clovis CA and the full system in 2000 while having a few diesels to help Fen-Pac needs an electric locomotive of a singular type that is robust and able to haul anything from ore drags to high speed stack trains.
here are the criterias for this locomotive
it needs to be easy to find and easy to afford
it needs to haul lionel maxi stacks in a team of 2 or 3 with 10 or more husky stacks at 40 plus scale mph or 40 or more ore cars at 20mph
it needs to be easy to convert to overhead power.
