“The support of the team from ISS has been instrumental in helping deliver JLU2 over the last 18 months. At SMD 3 new Transformer/Rectifiers were commissioned over 3 weekends involving a complex staging strategy whilst ensuring no loss in operational availability to the Jubilee traction network. 3 further TRUs were then commissioned at other sites. With staged handbacks every week for 12 weeks, the ISS team worked tirelessly in the pre-commission and commissioning phases to ensure a successful handback. The scale of the work undertaken and completed was huge and we were delighted to have ISS as part of our team”.
