Chiltern Railways has quietly scrapped its plans to introduce hybrid trains from services in London after reports of “unacceptably poor” air quality in the area surrounding its Marylebone terminus, the Standard can reveal.
The Arriva-owned operator last year introduced trial rolling stock which used batteries in combination with a diesel engine in a bid to reduce emissions in city centres. But it has since abandoned the project with the train no longer in service at present. The firm said increased costs meant the technology was no longer viable.
