Hi,
From what I remember the original post was by hotbiscuit2006, his website at http://www.trainz2006freewaredownloads.fusiveweb.co.uk/ only shows 1 route (Central Trains Network: Liverpool Lime Street, Leicester, Derby, Norwich) when you click Routes at the top.
Last post I think was at the start of the month saying it had been delayed, hope there is an update "soon".
