CHELMSFORD celebrated its city status this week as Greater Anglia named a class 90 locomotive in its honour.
Chelmsford was officially granted city status last year as part of the Queen's Diamond Jubilee commemorations.
Ruud Haket, managing director of Greater Anglia, said: "We're delighted to name a locomotive City of Chelmsford marking the importance of Chelmsford as a thriving regional centre and gateway to London.
"Many thousands of our customers commute daily from the station and we're proud to recognise city status for Chelmsford in this way."
Councillor Ron Alcock of Chelmsford City Council approached Greater Anglia last year with his idea.
He said: "It just feels right that after being bestowed with such an honour as city status, we are now celebrating with the naming of a locomotive that we can all enjoy seeing pass through the station each day.
"The railway has brought great economic benefits to Chelmsford, enabling our skilled workforce to commute in and out of the city each day."
