It is reported that Cardiff Bus have a Volvo 7900E electric demonstrator in use on service 6 with charging equipment in Cathays Park. The trial was due to run from 18 May for 8 weeks. I shall be in Cardiff on Friday 6 July and would like to sample this bus. Can anyone advise if the trial has been running successfully and if the bus is more likely than not to be running on Friday? I realise that that nothing is certain in bus operation but I don't want to waste my time waiting for it if there is little likelihood that it will turn up.
