Exactly what can be done with Ealing Broadway station was a subject of much discussion at a meeting of Crossrail engineers, residents and transport experts recently.
Some people hope a bus depot can be built on top of the railway to create a major interchange like that in Hammersmith, while others are unsure if Ealing could accommodate such a huge development.
What is certain from our archive photographs is that Hammersmith Broadway has undergone profound changes over the decades - though it has long been an important transport hub.
The area is almost unrecognisable in an early, undated photograph from a time in which horses and carts still ruled the roads.
On the side of The Swan pub is a vast billboard which points the way to the railway station, reading: 'The City Railway - best and cheapest rout [sic] to King's Cross, Farringdon, Moorgate, Bishopsgate, Aldgate and all parts of City and East End, New Cross, and South Eastern Railway; also St John's Wood, Harrow, Rickmansworth and Chesham. Paddington - Great Western Railway.'
In the foreground, an amputee in a bowler hat crosses the road on crutches, and a porter uses a rickshaw-type device to haul around a heavy load.
An image from around the same time shows an illumnated sign on the side of a restaurant - also called The Swan - with another cut-out hand pointing the way to the Lyric Theatre, which at the time was in a different location a short distance away down King Street.
The Lyric opened in 1895 and began life as an intimate opera house with a lavish auditorium designed by the prolific theatre architect Frank Matcham.
Its fortunes wavered over the next 70 years, and in 1966 it was forced to close its doors to make way for new shops and flats.
The move was met by a public outcry, and instead of facing outright demolition, the theatre was dismantled piece by piece and reconstructed in a concrete box two floors above King Street.
The new Lyric, including a black-box studio and café, was opened by the Queen in 1979.
In the early part of the last century Hammersmith was well known for having two public transport hubs - a trolley bus depot opposite Fulham Palace Road, and a bus garage known as Riverside, which was originally a mansion.
A more recent photograph shows the extent to which changes in modes of transport have influenced Hammersmith in the decades since.
Slicing through old rows of shops and houses, the flyover of the A4 carries blurred lines of traffic to and from central London with barely a moment to catch sight of the once-prominent exterior of St Paul's Church.
Behind it, the construction of the vast Broadway Centre gathers pace above the existing railway station.
The site, initially known as Centre West, was used for the opening credits of BBC comedy Bottom, with Rik Mayall and Adrian Edmonson staring out from the window of a half-built office.
