Recommendation: 2014-016

Basis for Recommendation

The cable involved in the accident did not contain the protective braid which was present in these components on original construction, and in addition to this a number of the free lengths on the traction cables were measured to be greater in length than the figure detailed in the design drawing, as a result the RAIU make the following safety recommendation:

Recommendation

Transdev should ensure that Alstom, as the contracted VMC, review the requirements for traction cables in the MIC bogie and produce and implement a suitable specification for this component. Installation procedures should also be reviewed to ensure that the free length requirements of these components are fulfilled
