Knorr-Bremse Rail Services (UK) has secured an eight-year contract from Alstom to repair and overhaul 510 sanitary systems fitted to the Class 390 trains. The original systems were supplied by Evac, which Knorr-Bremse acquired in June 2021. This acquisition brought the Evac product range into Knorr-Bremse’s rail solutions portfolio.
The extensive programme will be carried out at Knorr-Bremse’s dedicated facility in Wiltshire. The company says the long-term agreement underlines both the proven quality of Knorr-Bremse’s sanitary technology and Alstom’s confidence in the company’s ability to deliver specialised aftermarket services. With more than 200,000 sanitary systems delivered worldwide, Knorr-Bremse is now a global leader in this field.
The overhauled systems will improve the reliability and comfort of the Alstom-built Class 390 fleet, which serves as a backbone of the UK’s West Coast Main Line. Featuring advanced vacuum technology, the systems provide passengers with hygienic, water-efficient wastewater disposal.
The repair process will see each unit stripped down at the Wiltshire facility after removal at Alstom’s Manchester Traincare Centre in Longsight. Key components including vacuum pumps, sliding gate valves, and solenoid valves will be inspected, refurbished, or replaced as required. Every unit will then undergo rigorous testing before being returned to Longsight for re-installation.
