 In 2019 the railroad purchased a couple of Tier 4 low-emission locomotives, or KLW SE24B, that were built by the Knoxville Locomotive Works.Like the gensets, the railroad was granted $3.7 million from the Bay Area Air Quality Management District to purchase the locomotives.The president of CFNR, Brad Ovitt, said about the purchase, "We’re grateful to the Air District for making the purchase of these two low-emission, state-of-the-art locomotives feasible, as they provide benefits to the communities served by the railroad that would not be possible for us to do on a stand-alone basis.
