The trial was financially backed by EMR, Porterbrook, and the Department for Transport. East Midlands Railway (EMR), in collaboration with rolling stock firm Porterbrook and emissions specialist Eminox, has conducted the trial of a new emission reduction technology. As part of the testing, a two-box emissions reduction system was attached to the exhaust of a Class 170 train running between Derby and Matlock.
The $830,490 (£600,000) trial was financially backed by EMR, Porterbrook and the Department for Transport delivered by Innovate UK through its funding programme.
This system deploys an oxidation catalyst, along with a filter to partially eradicate pollution from nitrogen oxides, carbon monoxide, hydrocarbons, and particulate matter. A low volume hydrostatic oil reservoir, developed by Bosch Rexroth, was also included as part of the testing.
