The confirmed list for the event includes fifteen different classes, both in preservation and currently in main line operation.

Tickets, including money-saving multi-day rovers, are available from the SVR website.
Severn Valley Railway, which is based in Kidderminster, said, “We've worked hard to deliver a line-up that's worthy of such a momentous occasion as the 50th anniversary of diesel preservation. And I think everyone will agree, we've certainly delivered on that!
“This is a diesel event on a scale that hasn't been previously seen and we're looking forward to welcoming passengers from across the enthusiast fraternity to join us in celebrating the work and dedication of diesel preservationists over the years. Plus there's the chance to clock up some serious mileage behind our impressive selection of locomotives.”
