Love the note on their twitter feed on the website
Put it on your diary now. In 18 months, Sat 12 Nov 2016, @Railfuture national rail conference in Birmingham. More details later this year.

Planning ahead is quite common in the rail business - I was asked in January if I would be available for a talk to the Pewsey Vale Railway Society in 2016, and we've had apologies for absence at our TransWilts Link meeting which is every six month, new date typically notified in the minutes of the previous meeting, because that's "too short notice".
