The three-storey building, in Maskew Avenue, has been built for GB Railfreight and features a control room, three classrooms, a board room and staff welfare facilities.
The £3.6 million centre, which has taken 10 months to complete, replaces a temporary building and will allow GB Railfreight to expand its operations and various teams under one roof.
John Smith, managing director of the £225 million turnover GB Railfreight, which is one of the fastest growing companies in the railway sector, said: “Thank you to construction company Lindum for completing an outstanding job.
“Our partnership with Lindum has seen the works happen on time and within budget – no mean feat considering what a challenging year 2020 was for the UK and the whole world.
“Now we look to put that disruption behind us and kickstart a new phase for the business.”
Founded in 1999 and headquartered in London, GB Railfreight is the third largest rail freight operator in the UK.
Darren King, director of Lindum, in Newark Road, Peterborough said: “This has been a fantastic project to be involved in. The building is just a few miles from our office, so we are particularly happy to see the site being regenerated in this way.
“Work began just before the Covid outbreak so we had to introduce strict hygiene rules and extra safety measures on site to ensure the impact of the virus was kept to a minimum.
“It is great to see a company like GB Railfreight reaffirming its commitment to Peterborough and we’ve enjoyed working with such a forward-thinking and ambitious client.”
During construction, the project team planted a time capsule under the foundations.
This included newspapers, project drawings, team photographs and even a CD of current chart hits.
