The Watercress Line's Three-Day Diesel Gala returning

The Watercress Line’s Diesel Gala returns to Hampshire for three days of high-octane heritage rail excitement from July 10 to 12.

The event will feature a packed programme of locomotive appearances, onboard experiences and family-friendly activities, delivering what organisers promise will be a “thrilling celebration of diesel power” on the line’s famously steep gradients.

Rebecca Dalley, CEO of The Watercress Line, said: "We can’t wait to welcome visitors to this year’s Diesel Gala which promises to be a real celebration of railway heritage.

"There will be some fantastic visiting diesel locomotives on the track, as well as our own home-fleet engines.

"There will be plenty of activities at Ropley and visitors can hop on and off at the heritage stations – so don't miss out, book your tickets for a memorable day out."

A standout attraction at this year’s gala is Class 60 no. 60099 Ben More Assynt, which will make history as it will be the first time it has ever run on any heritage railway.

Powered by a Mirrlees Blackstone eight-cylinder engine producing around 3,100hp, the Class 60 is built for hauling heavy freight and currently moves large volumes of aggregates for major construction projects.

No. 60099 appears courtesy of DCRail and will run on Saturday and Sunday only, alongside Class 56 no. 56103, another freight locomotive from the same operator.

Other guest locomotives include the only complete 4VEP unit, 3417 Gordon Pettit, on loan from the Southern Electric Traction Group and Bluebell Railway, and the recently overhauled Class 31 no. 31210, courtesy of Jason Hall.

The Watercress Line’s own diesel fleet will also be in action, including Class 11 no. 12082, Class 08 no. D3462 (08377), Class 20s D8059 (20059) and D8188 (20188), Class 47 no. 47579 James Nightall GC, and Class 150 no. 150231.

Visitors will have the rare chance to ride behind Class 08 no. 08288 Phoenix, which usually serves as a shunting locomotive.

Static displays will feature Class 08 no. 08032 and Class 50 no. 50027 Lion.

Beyond the trains, the gala will include guided tours of the engineering workshops, miniature railway rides, society stands, gift shops and onboard selections of local ales and cider.
