A、The low efficiency of their operation. B、Competition from other modes of transport. C、Constant complaints from passengers. D、T

W: There’s is an element there about competition though, isn’t there? Because British railways are a nationalised industry, there’s only one railway system in the country. If you don’t like a particular can of baked beans, you can go and buy another; [1] but if you don’t like a particular railway, you can’t go and use another.
M: [2] Some people who write to me say this. They say that if you didn’t have a monopoly, you wouldn’t be able to do the things you do. Well, I don’t think we do anything deliberately to upset our customers. We have particular problems. Since 1946, when the Transport Act came in, we were nationalised.
W: Do you think that is a good thing? Has it been a good thing for the railways, do you think, to be nationalised?
M: Oh, I think so, yes. Because in general, [3] modes of transport are all around. Let’s face the fact. The car arrived. The car is here to stay. There is no question about that.
W: So what are you’re saying then is that if the railways hadn’t been nationalised, they would simply have disappeared?
M: Oh, I think they would have. [4] They’re disappearing fast in America. Er, the French railways lose 1 billion pounds a year, the German railways, 2 billion pounds a year. But you see, those governments are prepared to pour money into the transport system to keep it going.
W: So in a sense, you cope between two extremes. On the one hand, you’re trying not to lose too much money. And on the other hand, you’ve got to provide the best service.
M: Yes, you’re right.
