You are quite right. Look at what I said about 1410. You'd think it difficult to re-furbish the fleet into standard livery but they got the Temsa Avenues; 4721-6 not done as yet for some unexplained reason, without too much fuss.

It's the mechanical side of things that needs addressing. Getting rid of all the niggling issues that seem to blight our fleets. Problem is that the vehicles are hard worked and aren't off the road long enough. It's a bit catch 22.
