The fact that the reliability of the Class 360 fleet is lower then it should be is simply down to the poor maintenance under Greater Anglia, if they were kept well maintained then there would be no reason for the fleet to have such low reliability.
Least as maintenance is now back with Siemens, the reliability levels should increase but it will take time due the level of neglect the fleet got under Greater Anglia.
The maintenance of the 360’s has always been with Siemens since initial delivery during FGE’s tenure.
The drop in reliability is simple enough, Siemens at Ilford were being shown the door with the departure of the 360’s. Future prospects for the staff at Siemens Ilford were thin and for some completely non existent as the only transfer options to remain with Siemens were other Siemens sites nearby.
Many staff therefore left for pastures new, some shifted over to GA and some to Bombardier given the relatively secure future maintaining the Aventra’s at Iford, others left Ilford and Siemens completely.
With all the experience that quickly departed and the short staffing levels, the fall of MTIN was to be expected.
Happens time and time again with fleet cascades and renewals, lots of uncertainty / lack of job security etc all have an effect.
For those quick to bash the GA fleet teams please have a look at the last few years performance for the legacy / BR era fleets prior to disposal, notably the class 90’s, 321’s and 315’s. They have been pumping out record levels of performance, for some fleets the best performance in their lifetimes and sadly just prior to being cut up.
Hopefully now the 360’s have a certain and secure future, Siemens can regain the performance we all know the 360’s can achieve.
Fingers crossed for some large investment in the planned refurbishment too.
Successive short term contracts with little chance of investment return really did leave the fleet looking worn and tired. No TOC or ROSCO in their right mind would pay for a full refurbishment given the constant extensions and uncertainty of the Greater Anglia franchise over the last 10 years since NX departed.
