The industry leader behind bringing the groundbreaking Class 93 tri-mode locomotive to the UK says it’s time to rewrite the rules, not time to rebuild the railway.

Watts has published a paper to the industry, ‘Rail freight … a path to the future’, setting out the keys to unlock the network for more freight.
