Diesel Locomotives
As Pannier tanks were phased out, and diesel replaced steam across the British rail networks, the BR Class 14 locomotives found their niche in the Forest of Dean. While their working lives were short, as their intended work dried up shortly after introduction, many of them survived into preservation after having been sold into industrial work. Today, the DFR is home to two Class 14s, as well as a mixture of other mainline and industrial engines.
