To ask the Secretary of State for Transport, how many trains and what proportion of operators continue to release human waste and effluent on tracks in England and Wales.
9 July 2020
The following franchised train operators have varying quantities of trains that are not fitted with controlled emission toilets (CET): Chiltern, CrossCountry, EMR, GWR, Greater Anglia, Northern, WMT and Transport for Wales. Other operators, such as charter and heritage, for which the Department is not responsible for also operate trains that are not fitted with CET equipment.
Out of a national fleet of over 14,000 carriages there are approximately 350 that still discharge waste to the track and all of these will be refurbished or replaced.
