869271180 T1348 Assessing the benefits of enhanced freight speed differentials on the GB network

RSSB is seeking to procure research to assessing the benefits of enhanced freight speed differentials on the GB network. This project will determine and agree the criteria that a train must satisfy in order to safely travel at enhanced freight speeds, up to the maximum speed of the wagons. It will review if assumed braking capabilities in GKRT0075 and GMRT2045 are too conservative and can allow eligible freight trains to travel at an EF speed. This will be done by proposing a set of EF speed differentials for freig...
