The tramfacts site reported that an SNP MSP had mentioned trolleybuses on Newsnight Scotland. Unfortunately I found out too late to watch the programme on the BBC News player, but this comment on the Scotman website reports that Alex Neill MSP mentioned the trolleybus system planned for Leeds.

In response to the comment made on the tramfacts site about trams still being investigated in Leeds, this is true, but the trams mentioned in the West Yorkshire metro site are really "tram-trains" which are designed to run on exsiting heavy rail lines for most of their routes. These are not the type of trams currently planned for Edinburgh, which will use no existing railway lines.
