The SD70ACU was first built by EMD and later rebuilt by Norfolk Southern. It is originally an SD90MAC (or better known as a SD9043MAC) that has been rebuilt to renew its Mitsubishi electrical components and replace the cab with the new EMD Phase-II cab to comply with the most recent safety requirements. These locomotives are similar to the SD70ACe model, but the main body features are all reminiscent to the SD90MAC features. |
