Siemens Mobility employees delivered over 1,200 volunteering hours over seven weeks in nine locations across the UK.
Teams worked on local projects from Glasgow to Chippenham, including station improvements and environmental activities.
Work was carried out with community rail organisations and local charities.
Rob Morris, joint UK&I CEO and managing director for rail infrastructure at Siemens Mobility, said: “At Siemens Mobility, our colleagues don’t just transform rail travel and transport, they also demonstrate an extraordinary commitment to strengthening the communities where we live and work.
“The Spring Volunteering Campaign is a powerful reminder of the difference we can make – whether it is revitalising community spaces or lending a hand on local projects.
“The dedication shown by our teams across the country is a testament to our shared values and sense of community.”
In Stevenage, Siemens Mobility employees supported Generation Stevenage, a local careers fair, volunteering to promote rail and engineering careers to young people.
In Birmingham, teams hosted work experience days and worked with The Conservation Volunteers to extend community planting areas.
In Manchester, volunteers cleared weeds and planted flowers at Mauldeth Road Station.
Meanwhile, in York staff helped at Poppleton Community Railway Nursery by replacing cold frames and laying weed barriers.
In Glasgow, employees improved green spaces at Stobhill Hospital in partnership with The Conservation Volunteers.
Tim Elsworth, a volunteer from Poppleton Community Railway Nursery, said: “Volunteer visits from groups such as Siemens Mobility, provide a much-needed workforce on projects.”
