Sir: There is a good reason why Dr N P Meyer (letter, 11 December) saw a train being transported by road. The high track access charges imposed by Railtrack under the privatisation agreements have led to the preposterous position whereby it is often cheaper to transport trains needing repair on low-loaders than to haul them over the track.
This is the same sort of internal pricing structure which has caused BBC radio programme makers to find it cheaper to go out and buy CDs than to rent them from the BBC record library.
Clearly, logic plays little part in public service businesses.
