(23 Sep 2015, 11:01 am)Dan wrote Deptford's Volvo B10BLE/Wright Renowns 4904 (W904 RBB) and 4905 (W905 RBB) are now at Thornton Brothers, Ashington, to receive DDA modifications. Similarly, Riverside's Volvo B10BLE/Wright Renown 4907 (W907 RBB) is now moving under its own power again, having received a new engine from now-withdrawn "Toon Link" branded Volvo B10BLE/Wright Renown 4841 (R841 PRG), and is also at Thornton Brothers, Ashington, to receive DDA modifications.What do these DDA modifications involve?
ie what do these vehicles need that they haven't already got?
I cannot imagine that the interior is being changed to low-floor.
Is it mainly the fitting of entrance ramps?
