PRESS RELEASE – dated 14th August 2023


On Friday 4th August 2023, preparations were underway at Williton for a static test of ‘Hymek’ D7018 after some adjustments and checks had been made to the transmission. Following the engine start and while the preparations for the actual test were still in progress, the locomotive started to move uncommanded. This was against the parking brakes and included riding over scotches (or wheel chocks). The movement was only stopped by shutting down the engine. Some minor damage resulted, both to the locomotive and to some of DEPG’s equipment and spares. Thankfully, no-one was hurt in this incident. The Rail Accident Investigation Branch (RAIB) and the Office of Rail & Road (ORR) were informed routinely.

As an immediate consequence, an extraordinary meeting of the DEPG Board of Trustees has taken the decision to cease all operational ‘Hymek’ activities until further notice while we review the cause of the incident and develop additional controls to ensure that these precious locomotives remain safe to use.

This regrettably means that the planned ‘DEPG at 50’ celebrations at the end of September must be postponed until a later date. We particularly regret that neither ‘Hymek’ D7017 or D7018 will be able to attend the Severn Valley Railway’s ‘Magnificent Seven’ event in the Autumn as working locomotives. We recognise that this will disappoint many of our fans and followers, but it will be appreciated that the safety of both the public and our own volunteers cannot be put at risk.

Martin Howard
Chairman, DEPG Board of Directors and Trustees




We apologise for this unexpected and disappointing situation and for any inconvenience resulting from it. We are looking for additional engineering help to look after our fleet of elderly locomotives, so if you have such skills and would like to join the DEPG and come along to Williton for a ‘taster day’, then please use our CONTACT FORM so that we can get in touch with you.
