LYDNEY TRAIN FIELD GUIDE
Diesel Gala in the Forest: Two Days of Raw, Mechanical Sound Along Lydney’s Heritage Line
A focused, two-day celebration of resident and visiting diesel locomotives on the Dean Forest Railway — this guide explains what runs, where to catch it, and how to plan your visit.
Diesel Gala in the Forest: Two Days of Raw, Mechanical Sound Along Lydney’s Heritage Line.
The Diesel Gala is a concentrated weekend of diesel haulage across the Dean Forest Railway’s four-and-a-quarter-mile route in and around Lydney. Over two days the event brings together resident and visiting locomotives on an intensive timetable of passenger and goods workings, staged against tight curves and a prevailing gradient that makes northbound runs between Lydney Junction and Parkend especially dramatic.

What the weekend feels like
Expect a busy, locomotive-forward weekend: frequent departures from multiple stations, visiting engines rotated into service, and the constant presence of smoke, exhaust and mechanical sound as trains work the line.
