My Lords, I apologise to the House and the noble Lord, Lord Berkeley: I was a little late for the beginning of his opening remarks, although I did hear most of what he had to say.
I just want to say to my noble friend that on my journey to the House each week, I travel through the beautiful New Forest in Hampshire. This is the Weymouth to Waterloo line, so we travel at quite a speed. Across the section that covers the New Forest, there are crossings for pedestrians and for horse riders. As we approach a crossing, at a reasonable distance, the train driver is always required to sound the whistle. Would my noble friend consider whether that could be the answer for heritage railways—that the drivers of trains travelling at a much slower speed than the Weymouth to Waterloo train should sound the whistle? It seems to me that, if this has been satisfactory for so many years on a fast main line with South Western Railway, surely it would be adequate for heritage railways.
