The new railway station has been officially opened by Cambridge & Peterborough Mayor Dr Nik Johnson as the station opened five months ahead of schedule.
The first trains rolled into the station with Network Rail Chairman Sir Peter Hendy, former Mayor James Palmer and members of the local community present for the opening ceremony.
This marked the first time passenger trains had called in it a Soham in 56 years.
The new station means passengers in Soham can travel directly to places like Bury St Edmunds, Ely, Ipswich and Peterborough.
Easy connections can also be made on to Cambridge, Norwich, London, the Midlands, the North and Scotland.
The station was constructed over 12 months by Network Rail and its contactor J Murphy and Sons Ltd close to the site of the old station.
The £18.6m construction was funded by the Cambridgeshire & Peterborough Combined Authority including £1m in Local Growth Deal support.
Mayor Dr Nik Johnson spoke at the unveiling of a plaque which marks the opening of the station.
Mayor Johnson said: “Congratulations to everyone involved in this great enterprise.
“Cooperation and partnership have created a benefit of lasting value for this community and its future generations, opening a door into opportunity.
“We need more green, clean public transport for the public good - and this new station is proof that, together, we can make it happen.”
Greater Anglia will be managing Soham station with its trains serving passengers at the station.
Jamie Burles, Greater Anglia Managing Director spoke on the opening of the new station.
Mr Burles said: “We’re proud to be the train operator serving Soham with our high quality new bi-mode trains and to be the operator responsible for managing the new station.
“It’s not often that new stations are opened and even rarer that they are then immediately served by new state-of-the-art trains.
“We know the opening of the station has been much anticipated.
“We’re committed to continuing to offer an excellent service on this line and across our network.”
During the opening a second plaque was unveiled to honour the four railway workers caught up in the Soham Rail disaster on 2nd June 1944.
