Shepherds Bush central line station has re-opened, following an eight month closure to completely re-build the structure.
The old ticket hall of the 108-year-old station was demolished and rebuilt with double the number of ticket gates to increase capacity.
Mayor of London Boris Johnson, said: "I am committed to ensuring that the upgrade and improvement of the tube network continues, and I'm pleased that we have delivered this renovation.
"The station has been remodelled to the highest modern standards, and will provide a hugely important resource to both the local community and to visitors of the new Westfield centre, which is set to play an important role in the regeneration of the area."
London Underground's Strategy & Service Development Director, Richard Parry, said: "The station, which was originally built in Victorian times, has brand new escalators for the first time in 80 years and a stunning new ticket hall with much greater capacity.
"This key Tube station will be the principal gateway to the new Westfield centre, as well as serving the busy local area, with passenger numbers using the station forecast to roughly double once the new centre opens. The improvements mean the station will be able to cope with this increased demand.
"Major transport benefits are being delivered through our Investment Programme and as part of the £170M funded by Westfield London, which will be a benefit to local residents and businesses and enable the majority of visitors to the new centre to travel by public transport," nhe said.
A new Underground will open on the Hammersmith & City line at Wood Lane, before 30 October, and will be the first new station on the existing Tube network for 70 years.
Further improvements to the area include:
A new fully accessible bus station next to the new Wood Lane Tube station. The bus station will see 170 bus movements every hour, with eight routes serving the station.
A refurbished White City Central line station and a renamed Shepherd’s Bush Market station on the Hammersmith and City line.
Four new cycle routes have been created and there are 570 secure cycle parking spaces around the site.
Pedestrian access has been upgraded with new crossings across Wood Lane, Uxbridge Road and the southern end of the A3220 and a step-free pedestrian route linking the A3220 to the development and to Wood Lane.
