Ian Prosser, HM Chief Inspector of Railways at the Officer for Rail and Road (ORR), said: 'Today I have authorised Kenilworth Station' on Twitter at just after 8.30pm last night.
The ORR then retweeted him, saying: "Great news, Kenilworth station moves a step nearer to opening."
However, a firm opening date has yet to be announced.
Following the news, the joint managing director of Warwickshire County Council Monica Fogarty said: "I am delighted to say that the ORR has passed authorisation for entry into service subject to a number of outstanding items being finalised.
"All partners have worked extremely hard to move this forward so that the station can open as soon as possible.
"Once these have been finalised, we will be in position to confirm the date for the station to open."
On Tuesday March 20, Ms Fogarty said the council had submitted all the relevant information to the ORR so it could make a decision on whether to authorise the station's use.
When the station opens, it will run an hourly service between Leamington and Coventry operated by West Midlands Railway. There will be no service on Sundays.
