The rail industry is aiming to give steam train and other heritage operators greater clarity on their safety obligations.
Britain's rail standards body RSSB is bringing together national rail and heritage interests to make it easier for operators to understand their requirements for running trains on the national rail network.
The new standards are designed to ensure popular rail tours such as the Jacobite between Fort William and Mallaig, made famous as the Hogwarts Express in the Harry Potter films, can continue to run alongside modern, conventional rail services safely and reliably.
The popularity and growth in the use of heritage steam and diesel locomotives, combined with operational experience, has led to a more structured framework of standards being proposed to help operators meet key safety requirements. They replace older obsolete standards which lacked detail and had failed to keep up with growth in the heritage sector.
RSSB is consulting on the new standards, and subject to final agreement with Network Rail and train operating companies, could be published in December 2017.
