First 3D printed parts successfully trialled on UK passenger trains

Angel Trains, Stratasys, DB ESG and Chiltern Railways joined forces to trial the first 3D printed parts ever deployed within an in-service passenger train in the UK.

These parts include four passenger armrests and seven grab handles, which have been installed on Chiltern Railways trains. The trial’s success to date demonstrates how 3D printing can help train operators accelerate the replacement of obsolete parts, enabling them to get vehicles back into service quicker and better maintain their trains – improving the quality of service for passengers.

The cross-industry collaboration between Angel Trains, DB ESG and Stratasys aims to leverage 3D printing to help overcome issues around the replacement of obsolete parts across the UK rail industry. Unlike the automotive industry, where vehicles from household brands are mass produced in their millions each year, the number of fleets in the rail industry are comparatively very small and, in some cases, over 30 years old. This combination presents several challenges for train operators, especially when it comes to vehicle maintenance and part replacement.
