    You have missed out, or not seen the piece about a collaboration with Siemens.

    Wonder what that could be all about????

    Now the loco is back at Barrow Hill it will be sheeted over and remain outside to facilitate a thorough clean and to allow it to dry out. This may take up to 4 weeks.


    Once the loco is inside, a thorough assessment and testing of the traction cabling, switchgear and protection equipment will be carried out. It’s not been possible so far, due to the need to preserve evidence and working through the Insurance Company’s forensic engineering process. A worst case scenario is that all of the traction cables will need replacing. Estimated worst case cost £25,000.


    In order to obtain insurance cover in the future and to limit the possibility of such catastrophic damage in the future, new protection equipment will need designing and fitting to our locos. This will be filters to absorb high voltage surges that occur during fault conditions and events like wheel slip at high speed or traction current overload. The design work and approval of the changes will require professional support. Estimated cost £30,000.


    Asbestos has been found in two traction motor armatures and two field coil frames that need to be rewound as part of repairing the damage sustained when D9009 failed near Prestonpans on 03/03/2019. We may not be able to recover the cost of removing it through our insurance. Cost £15,000.


    A briefing will be provided at the Society AGM about what is likely to have happened on 03/03/2019, lessons to learn and improvements we can make for the future. To donate, please CLICK HERE.

    Has the "power surge" been explained?

    Think it is confidential between the insurance company and The DPS.

    The list of possibilities was :-

    1. A Lightning Strike
    2. A Dropper cable from the Catenary grounding on the loco.

    A explanation was promised, however, the loco should also have had earth bonding straps between the body and bogie, and evidently these were missing.

    This all came out of a conversation on Martin Walker's excellent 55022 page on Facebook, so don't shoot the messenger.

    Thank you, I've seen it. Seems as though a lot of new/expensive wiring is needed. My money is on 'touched the overhead power line' as the cause of the incident.
