Oh, yes. The nationalisation of transport has not in any way interfered with the machinery of inspection of the Ministry of Transport into any accident of this character. The hon. Member who referred to a specific point as regards the alteration in the signalling methods or machinery, is, I think, very well aware that to apply his suggestion to the mainline railways would be an enormous task and would require the very serious and full consideration of any body which was responsible. It would depend on the capital resources, and the men, material and other factors available.
