Dave Kornfeld reports: DLW has had a 251 update program ongoing, featuring "fuel efficiency" kits developed at their Lucknow Research Centre. Additionally, there has been an ongoing program of replacing the old ALCo turbos with modern GEC-Napier turbochargers. This program has also been deemed a success, as fuel efficiency has increased, along with an increase in traction horsepower. Unfortunately, the heavy black smoke emission during transient (acceleration) conditions has been abated to a very obvious degree.
