Royal Mail is set to make more use of trains to carry post in Britain, it is reported. The Daily Telegraph says Royal Mail chief executive Simon Thompson wants to ‘at least treble’ the volumes carried. Most mail trains were withdrawn earlier this century in favour of large lorries and planes and briefly scrapped altogether. A residual service was restored in late 2004, and three trains a day still run between London, Warrington and Shieldmuir, south of Glasgow. Talks are said to be in progress between Royal Mail and Network Rail to agree paths and timings for more postal trains, but Royal Mail has so far declined to comment.
