List of low-emissions locomotives

From Wikipedia, the free encyclopedia

The following is a list of diesel-electric locomotives that meet or exceed EPA Tier 2 locomotive emissions regulations, sorted by builder. This is a non-exhaustive list of locomotives in the US only. Furthermore, green/clean energy is an always developing sector and that more locomotives may be added to the list, while some will no longer meet current standards.
