I remember Justin mainly through his involvement in APTU - The rail traveller's User Group on Thameslink - he had a particular interest in services to / from Cricklewood station (and, of course, the station itself) - the users of this station will miss the championing and lobbying he did on behalf of the stations travellers. In particular he was passionate about retention of services there should Brent Cross be opened. I also know that he had many other areas he supported and championed – an eclectic mix of statistics, cricket, bridge and Europe. I will miss him. Neil
