A landmark railway station in Melbourne's west, which opened less than three years ago, is already failing to cope with demand and commuters who drive to the station risk fines every day for illegally parking.

The $110 million Williams Landing station opened in April 2012 and is used by commuters in the boom suburbs of Point Cook, Truganina and Williams Landing, which are forecast to collectively house about 90,000 residents by 2030.

Yet the station has just 500 parking spaces and is served by buses that run at 20- to 22-minute intervals in the peak along choked arterial roads.

Predictions before the station opened that it would be swamped have proved true, with Wyndham City in recent months taking to fining motorists, including commuters, who illegally park near the station. The council issued more than 900 fines last year. It also issued almost 1300 fines around Hoppers Crossing, the next station down the line.
