UP SD60M question.

It will probably be a necessary item when Tier IV Emissions appear.

That ain't gonna cut it for sure , it's gonna take more than gimmics to bring an older EMD into even tier 1 compliance. More to come , stay tuned.

One of dozens of clever and expensive gadgets to cause a more complete fuel burn , lower emissions and extend the service life of the locomotive. I must add that most if not all of these things have little or not effect execpt to cost time and money.

Last week I saw UP 2368,an SD60M,with this info. under the cab."First retrofitted U.S. road locomotive with oxidation catalyst aftertreatment." Could someone explain what this retrofitting consisted of,and for what purpose?
