Multiple modifications for Porterbrook’s Class 90 locomotives

Vossloh Kiepe UK is carrying out a number of reliability, maintainability and safety modifications to 15 Class 90 locomotives owned by Porterbrook and operated by Abellio Greater Anglia. Four upgrades and reconfigurations promise to enhance performance and improve reliability, benefitting passengers.

The first will be an upgrade to the Inergen fire system: a new relay panel and electronic pressure switches are being installed together with new protective sleeving and in addition all Inergen fire system hoses will be renewed during the locomotives’ downtime.

New, more reliable state-of-the art head and tail lights are also to be installed: the new lights should significantly reduce the amount of maintenance time required in future and improve vehicle reliability. The Class 90 locomotives will also be benefitting from an upgrade to the auto power control system.

Having been fitted originally with a conventional APC receiver, the current unit is no longer available, but the change to a modern solid state type will improve reliability. Finally, the blower motor current detection circuit will be re-configured to enhance performance. Operations Director Brian Parsons said: “Managing so many upgrades and modifications at one time is a test of our project management, but it will ensure that we minimise the length of time the locomotives are out of action. In total, for all 15 locomotives, we expect the project to take just 16 weeks. We’re procuring some of the materials whilst other material is free issued, and we’ll be creating installation procedures for two of the
modifications.”
