Harness Couplers in Coaches

In pre-2011 coaches we used to have this kind of arrangement:

 Front side is power cable, back side is the control connectors.
 These days we have harting connectors for both power (440V) and control 110V connections to RMPU

 Recently we found some harting couplers failing in new coaches.




Inside view of the harting connectors.
Should we re-designh these connectors or simply relocate them to prevent failure due to water ingress?
See how they have failed:
