ULTRA violet lights fitted in the toilets of Swindon railway station to combat drug misuse may not be doing the job, says train company First Great Western.
The green lighting is designed to prevent drug addicts from injecting heroin because they make it difficult to see veins.
They were installed in May following the death of 19-year-old Kellie Marie Oakes, which is believed to be drug related, after she was found unconscious in the men's toilets of the station.
Elaine Holt, commercial director at First Great Western, said: "They have been put in following the tragedy but we are not sure whether they are actually reducing drug use.
"Addicts may actually draw their veins before entering the station toilet. We attract all sorts of people here, they do congregate because we are in the centre of town so it's not unusual to get this kind of problem.
"We need to get more customer feedback. We've had some negative responses because customers are saying that the lights are too dark."
Similar initiatives are taking place at Bristol Temple Meads, Bristol Parkway, Newport and Reading stations.
