UK research could lead to more efficient freight trains

Sustrail, the EU-funded sustainable freight railway, combines design innovation with lightweight materials to optimise geometry, axle load and ground stabilisation for its freight vehicles so they have less impact on tracks, while also being quieter and faster than existing stock.

‘The SUSTRAIL vehicle is capable of running at up to 140km/hr with reduced track forces compared with conventional freight bogies,’ said IRR director Professor Simon Iwnicki. ‘It comprises novel running gear using components based on the widely used Y25 suspension which means that it can be maintained using established techniques, equipment and staff, alongside disk brakes and an electronic braking system to ensure safe operation at the higher operating speeds. Wheel sets with impact resistant coatings will reduce inspection costs, while on-board condition monitoring will allow longer maintenance intervals.’

The design of the SUSTRAIL freight bogie has been patented and a prototype has been manufactured and is currently being tested.
