Yes that was the loss of a real ‘interpretation and educational’ part of the now seriously dumbed down NRM theme park.The sad thing is at Ellerman Lines 35029 was rescued from Barry Scrapyard and sectioned to show how a steam loco worked. It had a drive unit beneath it to simulate operation etc. A wonderful exhibit to demonstrate the simple science behind the steam engine. All the money spent on the ‘lab’ at York but none spent on getting this exhibit operating again! A real missed opportunity!
